This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross-laminated timber (CLT) is a recent engineered wood material produced in a variety of thicknesses and lengths and used in for floor systems. The design of CLT floors has specific support and connection details that require evaluation on the performance of these mass timber structures. The serviceability criterion is one of the primary considerations for the adequate design of timber floor construction. Proposed design procedures consider the first natural frequency and deflection parameters. Nevertheless, there are many uncertainties concerning the factors that influence these parameters in a CLT floor structure. The main focus of the research project was on the influence of end support condition on vibration performance of CLT floor. The support condition was characterized by the rotational stiffness at the supported edges of the CLT floors. A second interest was the performance of CLT floors when supported in a double-span configuration. Experimental work was conducted to evaluate these influences. In addition, finite element analysis (FEA) modelling was conducted to supplement the experimental work. To obtain material property input into the FEA models, laboratory experiment was conducted to characterize the rotational stiffness of CLT panels measured with vibration and CLT material properties determined under static tests by CLT strips cut from the CLT panels. The results demonstrated the influence of the rotational stiffness tested with double-span setup on the first natural frequency and static deflection of the CLT floors. Also, the FEA modeling proved to be effective in predicting natural frequencies and deflections of CLT floors, with accuracy improving with the use of orthotropic material properties compared with isotropic properties. The presence of panel-to-panel joints in CLT floor was found to have a significant impact on the transverse system stiffness of CLT floor and should be properly accounted for in design if two-way orthotropic plate model is used. It is recommended that further research be pursued on floors supported on all four sides and by beams or columns, and multiple-span floors.

Book excerpt: Developed in Europe in the early 1990's, cross-laminated timber (CLT) is beginning to make its way into the North American building construction market. Similar to other types of engineered wood products, such as Glulam, CLT is an efficient and economical way to use natural wood resources. This report introduces the product with its structural characteristics, advantages and disadvantages, manufacturing, and construction. ANSI/APA PRG 320 Standard for Performance-Rated Cross-Laminated Timber published by APA - The Engineered Wood Association is the manufacturing standard for CLT in the United States. Manufacturers will supply reference design values for design engineers to check the strength of CLT members. Methods used to determine reference design values include experimental and analytical studies. CLT has many benefits in construction but also has challenges due to architects', engineers', and contractors' unfamiliarity with the product. A few projects have been built using CLT in the United States including a building at Oregon State University and one at the University of Arkansas.

Book excerpt: The development of cross-laminated timber (CLT) panel technology has opened up new opportunities for wood in tall buildings. Several characteristics including seismic performance and speed of construction have raised interest among designers. As CLT gains acceptance in the industry, alternative structural solutions need to be investigated to improve performance of CLT as a building material. The first study presented is an assessment of the viability of hybrid poplar for use in CLT panels. Hybrid poplar is a low density species, which is not typically considered for structural applications. Low density species have the potential to improve the structural efficiency of CLT panels. The tests conducted are based on the qualification of panels outlined in the ANSI/APA PRG-320: Standard for Performance-Rated Cross-Laminated Timber to determine the structural viability of the CLT panels. The second study presented is an investigation of a new alternative energy dissipation solution to be used with cross-laminated timber rocking walls for seismic design. The energy dissipators are designed as a structural fuse which can be easily replaced after failure following a large seismic event. The results of this study give insight to alternative solutions for CLT to improve upon current applications.

Download or read book Parametrically Informed Early Design Guidance for Mass Timber Floors for Embodied Carbon and Structural Design written by Samantha Leonard and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last decade, mass timber structures are gaining traction in the U.S. commercial construction market for a variety of reasons, including their prefabrication capabilities, low embodied carbon contribution (EC), ability to expose the timber for aesthetics, and their potential to reduce construction schedules and site work. Of these, the low material EC of timber structural elements can contribute to projects' sustainability goals while industry seeks to reduce energy use in construction and buildings. Because modern mass timber structures are relatively new, there is limited design guidance at the intersection of EC and structural design to guide practitioners' early-stage design decision-making. Therefore, the goal of this research is to fill in design guidance gaps for mass timber structures by answering questions about trends in EC and structural design, comparisons to baseline concrete floors, the impact of prescriptive fire design options, designing for acoustic insulation beyond code, and key design guidance for mass timber. To fill in the gap and address these questions, this research focuses on mass timber and hybrid mass timber floor systems. A parametric model was developed for five floor systems, all of which have cross laminated timber (CLT) floors. Two systems have glue-laminated timber (Glulam) framing, one with and one without infill beams. Two systems have steel W-shape non-composite framing, again one with and one without infill beams. The final is a timber-concrete composite floor system with steel shear connectors. The parametric model varied floor geometry, the number of infill beams, the prescriptive fire design approach, and system type to generate a set of approximately 5,500 designs. The designs were automatically sized using the smallest structural elements meeting requirements for flexure, shear, fire design, deflections, and control of walking-induced vibrations. The models assumed code minimum acoustic insulation; however, improved acoustic assembly options were catalogued and studied for their impacts on structural depth, mass, EC, and acoustic insulation metrics including sound transmission class (STC) and impact isolation class (IIC). The parametric modeling output for each design included minimum element sizes, system depth, material takeoffs, system mass, and EC. The results were used to study the impacts of design variables on performance metrics including depth, mass, and EC. Using the findings of this analysis, design recommendations were developed to inform early-design decision-making. Some key results and recommendations are summarized here. If reducing EC and mass is a main priority, consider sourcing the most sustainable timber available, avoid designs which are overly deep, avoid a steel hybrid system with infill beams, and limit designs to a maximum of a single infill beam where applicable and possible. If reducing depth is a main priority, select a steel-hybrid system to take advantage of steel's greater spanning capabilities, select a bay aspect ratio of 1.0 or greater so the steel girders are spanning the short direction, and design for small bay sizes less than 20 feet. When designing for fire, plan to select a minimum 5-ply panel for the combined fire design configuration for a 2-hr FRR with 40 minutes of char and 80 minutes of noncombustible protection. Plan to select a minimum 7-ply panel for the exposed fire design configuration for a 2-hr FRR with 2 hours of char. Due to the nature of parametric modeling to inform early design, there are limitations to this research to facilitate a clear analysis and understanding of the model results and trends. Connections informed boundary assumptions but were not modeled, the focus was on gravity loads only, systems were modeled at the scale of a single bay, loads assumed residential occupancy or similar loads, a single mid-range wood grade was assumed in structural calculations, fire design is based on prescriptive and conservative design procedures, and design for the control of walking-induced vibrations uses simplified procedures. Despite these limitations, model verification based on real case study projects found that the model produced realistic sizing results, and is considered valid for the scope and goals of this research. Future work that will come directly out of this dissertation includes the development of an interactive web-based tool and accompanying design guide based on the design guidance and recommendations for mass timber floor system design within this research. The industry would additionally benefit from further research related to this topic, including similar parametric studies of lateral systems, full-scale building analysis, studies into cost and scheduling, parametric studies of the contribution of connections, and research on the optimization of carbon storage versus building height, envelope area, and operational energy.

This book was released on 2013-09-25 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the contributions from the RILEM International Symposium on Materials and Joints in Timber Structures that was held in Stuttgart, Germany from October 8 to 10, 2013. It covers recent developments in the materials and the joints used in modern timber structures. Regarding basic wooden materials, the contributions highlight the widened spectrum of products comprising cross-laminated timber, glulam and LVL from hardwoods and block glued elements. Timber concrete compounds, cement bonded wood composites and innovative light-weight constructions represent increasingly employed alternatives for floors, bridges and facades. With regard to jointing technologies, considerable advances in both mechanical connections and glued joints are presented. Self-tapping screws have created unprecedented options for reliable, strong as well as ductile joints and reinforcement technologies. Regarding adhesives, which constitute the basis of the jointing/laminating technology of modern timber products, extended options for tailor-made bonding solutions have to be stated. Apart from melamine-urea and phenolic-resorcinol adhesives, one-component-polyurethanes, emulsion isocyanate polymers and epoxies offer a wide range of possibilities. The contributions dealing with experimental and numerical investigations on static, cyclic and seismic behavior of structures clearly reveal the enhanced potential of modern timber construction for reliable and sustainable buildings and bridges of the new millennium. The book is structured in nine thematic areas, being I) Structures II) Mechanical Connections III) Glued Joints and Adhesives IV) Timber and Concrete/Cement/Polymer Composites V) Cyclic, Seismic Behavior VI) Hardwood, Modified Wood and Bamboo VII) Cross-Laminated Timber VIII) Properties and Testing of Wood IX) Glulam

Available in PDF, EPUB and Kindle. Book excerpt: Cross-laminated timber (CLT) is a massive engineered wood product made of orthogonally bonded layers of solid-sawn lumber, and is intended for roof, floor, or wall applications. Although it was developed in Europe in the early 90s, CLT is relatively new to North America. CLT products must be certified for structural use. First North American product standard stipulating test methods and qualification criteria for benchmark structural properties and adhesive bond integrity in structural CLT is ANSI/APA PRG320-2012. These methods and criteria have been adapted from existing laminated timber products (glulam), sometimes disregarding substantial differences between parallel laminates and CLT, in which layers are perpendicular to each other. From the point of view of long term sustainability of the CLT industry in North America, the critical questions are: 1. Is it possible to use low-grade timber harvested in the Pacific Northwest region in CLT products without compromising critical engineering parameters? Utilization of low- grade lumber, which is typically under-valued, in value-added engineered products should reduce the pressure on the high end structural lumber supply and may also provide a substantial outlet for lower-grade lumber timber species, including beetle-killed pine (BKP) harvested in the affected areas. 2. Can alternative adhesive systems, currently used in related engineered wood products and manufactured by domestic industry, be successfully used in CLT production? This is an important question, and is related to the fact that polyurethane (PUR) is the primary adhesive currently used by CLT manufacturing industry, and is supplied worldwide by a single Europe-based company. This adhesive is optimized for the species commonly used in CLT products to-date. ANSI/APA PRG320-2012 standard allows alternative adhesive types (PRF and EPI are specifically named), but to-date, only one alternative (MUF) has been used in commercial products. The objective of this project is to determine effective adhesive systems and bonding pressures for the hybrid cross-laminated timber (CLT) combinations. A secondary objective is to evaluate the testing methods prescribed in PRG 320-2012 for cross-laminated bond integrity. Integrity of hybrid CLT layups was evaluated on small specimens derived from CLT billets fabricated in-house using test procedures and qualification criteria specified in ANSI/APA PRG 320-2012 section 8.2.3. Test results were compared to prescribed qualification criteria. The Hybrid CLT combinations for this study include both structural grade lumber and low-grade lumber. For a reference species, lodgepole pine was selected, since it is a member of the US-SPF group closely related to the European species commonly used for CLT construction. The structural-grade, local species will be represented by Douglas-fir, while the low-grade species will be represented by low-grade lodgepole Pine, Douglas-fir, and Western Hemlock. The two adhesive systems investigated were 1) polyurethane-based PUR (currently the most common adhesive used by the CLT industry), which will serve as a reference system, and 2) phenol-resorcinol formaldehyde (PRF), which will represent a potential domestic alternative. PRF was chosen because it is a cold setting adhesive commonly used by the engineered wood products industry in North America; however, no CLT manufacturers utilize this adhesive system. The variables included species combinations (6), adhesive types (2), and clamping pressures (3), with repetition of 9 specimens per combination coming from at least three different CLT billets. The specimen’s bond integrity was assessed by the qualification panel requirements in PRG 320-2012 section 8.2. The qualification tests are block shear and cyclic delamination. A combination must pass both of the test requirements to qualify. The results of the study show that, of the 36 combinations, six failed the block shear test requirements and twenty-five failed the delamination test requirements. The 10 variable combinations that passed both requirements were DDL10F, DDL40F, DPL40F, PPH10F, PPH69F, PPH10U, PPH40U, PPL10U, PPL69U, and PHL69U. Initial inspection of test results show that no single variable that seems to make a significant impact on the bond integrity. It did reveal that no combinations with the use of Douglas-fir as a face material and PUR as an adhesive met the requirement, and only one combination with western hemlock as a core material met the requirements. It is evident that the delamination test was the major restriction on whether or not a combination passes the bond qualification. We believe that the adaption of a delamination test standard designed for layers with parallel grains makes the passing requirement too strict for an orthogonally bonded product. In conclusion, there were 10 combinations that passed both bond integrity test requirements. It was unclear whether the species and/or grade combination, adhesive system, or clamping pressure made the biggest impact on the bond integrity. Relative to the reference adhesive (PUR), and species combination (lodgepole pine), the hybrid panels performed similarly and showed that certain species and/or grade combinations could pass the qualification requirements for specific requirements. The knowledge gained by this screening study will allow further qualification testing of the passing combinations per PRG320-2012. This also has the potential to supply the CLT manufacturing community with greater flexibility of manufacturing techniques and materials, as well as offer value to underutilized lumber.

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The Cross laminated timber (CLT) panels extended the market of timber material in structural construction, while its laminated structure allows layup design for utilizing low-value lumber. Through mechanical tests and numerical simulation, the mechanical properties of CLT made with low-value sugar maple (Acer saccharum) was first examined. The CLT panels made with white spruce (Picea glauca) salvaged from dead standing trees were examined. The mixed-species panels were prepared with the low-value sugar maple and salvaged spruce. The CLT panels were tested with the third-point and mid-point bending tests following ASTM D198 for major-axis flexural and shear properties. The CLT panels provided adequate flexural performance per current standard PRG 320-2019. The mechanical properties of the hybrid CLT panels with sugar maple surface layers were improved. In the meanwhile, the finite element model built with orthogonal constitutive law and progressive damage criteria simulated the mechanical behaviors of the tested CLT panels. Overall, the simulation results compared favorably with test data and provided reasonable estimates. A decomposed model with equivalent springs and shell elements based on the connection properties was developed to estimate the nonlinear dynamic performance of the conventional CLT shear wall. Full-size building simulation results indicated that the developed model could accurately estimate the wall dynamic performance. The dynamic performance of PT CLT rocking wall was also evaluated with numerical simulation. The similar equivalent decomposed wall model was developed and calibrated. A full-scale platform structure was simulated and compared with test results subjected to different seismic excitations. Because of the concentrated connection damage, the impact of sequential seismic-wind hazards on CLT shear wall systems is severer than that on traditional steel or reinforced concrete structures. With the developed conventional and PT wall models, the structural dynamic responses of different CLT wall systems were evaluated in wind-only and sequential seismic-wind scenarios. The wind-excited peak story displacement and acceleration for both CLT structures were magnified in the sequential seismic-wind scenarios compared with wind-only scenarios. The simulation results indicated that the sequential seismic-wind scenarios caused large acceleration with damaged connections for the conventional CLT shear wall structure. The PT CLT wall structure had minor displacement and acceleration, which was linear to the wind loading factors. The study of mechanical properties of the CLT panels made with low-value sugar maple and salvaged spruce can promote the utilization of the low-value lumber and promote forest management. The developed panel model provided an approach to estimate the CLT mechanical properties based on the nondestructive lamination test result, which can be a tool for future layup design. The developed decomposed equivalent wall models can capture the wall behavior effectively and efficiently, which potentially be an aid for the performance assessment of CLT structures. The results demonstrated the necessity of considering sequential hazard cases for conventional CLT wall structures, which is a reference for future development of performance-based design for conventional CLT wall structures.

Use of Cross laminated timber with two concrete examples" is my Final Project of Grade. This project summarizes the most common timber systems used over time. It studies thoroughly the wood product "Cross laminated timber", which is a relatively new wood product that was first introduced in the 1990's in Austria and has gained popularity in residential and non-residential buildings in many European countries and around the world in the recent past. Two specific projects of two existing single-family houses are designed with CLT solid wood panels. This paper is divided into three parts: In the first part an overview of the construction systems in timber construction is given. The systems are introduced, their characteristics and loadbearing performance are explained in a superficial way. The second part deals with Cross laminated timber. In this chapter, an extensive study of this wood system is carried out. X-LAM, its abbreviation, is introduced in many general aspects as a product. All the specific and technic information which is shown is, in particular, form the Austrian firm "KLH Massivholz Gmbh", which I had the pleasure and honour to visit. And in the final third part, two projects of two single-family houses are shown. Starting from a basic plan of the house, which have been obtained from two architects with which I'm truly grateful for their help, X-LAM system is used to design the house. Floor plans, sections, details and concrete component connections are designed.

Available in PDF, EPUB and Kindle. Book excerpt: Cross-laminated timber (CLT) has been developed and used in building applications, such as walls, roofs, and floors, which are subjected to long-term loading in the perpendicular-to-grain direction. Thus, the creep performance of CLT is critical in the design and construction of a building using CLT panels. The creep behaviour of a material, component, connection, or system is defined as the deformation increases with time under constant load. This thesis report examined the creep of CLT using the thin specimens. Two loading levels (60% and 30% of proportional limit (PL), or 93kg and 25kg), two relative humidities (30% and 65%), and two panel directions (major and minor). A total of four groups of thin CLT specimens were fabricated, and each group had six specimens (three for major and three for minor), producing a total of 24 specimens. The third-point static bending tests were performed to determine the load levels for creep tests. A constant load was applied on each specimen, and the flexural deflection was recorded in the course of loading. It was found that 1) In third-point bending test, the PLs of thin CLT specimens in the major and minor directions were 3,000N and 800N, respectively. The average MOE[subscript app] and MOR[subscript app] of the specimens in the major direction were 8,510 MPa and 46.64 MPa, respectively, and the average MOE[subscript app] and MOR[subscript app] in the minor direction were 809 MPa and 9.48 MPa, respectively; 2) With increasing load level up from 30% to 60% PL, the minor strength direction specimens deflected 81.04% than that of 30% PL. And for major strength direction specimen, the deflection increased 32.07%; 3) With decreasing the RH, the deflection of CLT specimens showed a slower increment. At the load level of 60% PL, the deflection of creep specimens in the minor direction showed a difference of about 2 mm after 7 days. However, at the load level of 30% PL, RH showed little impact on creep. 4) CLT in the major direction exhibited a superior load-bearing capacity than those in the minor direction. At the load level of 30% PL, the maximum deflection in the minor direction was about 1.8 times larger than that in the major one, and at the load level of 60% PL, the deflection in the minor direction was approximately 2.5 times larger than that in the major one. 5) The Burger model could well describe the 7-day creep of thin CLT specimens with a high r-square value around 0.9135 tested in this study. It could be recommended to investigate the long-term creep behaviour of full-size CLT members by taking cyclic humidity and edge-bonding into account for at least one to three months.
