This book was released on 2016 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: FEA models were developed and validated to predict shear strength and effective shear modulus of SCWF shear walls under monotonic loading. Moreover, the hysteretic behavior of SCWF shear walls was predicted using hysteretic behavior of sheathing-to-framing connector elements. Analyses were performed to assess the shear strength, stiffness, ductility, equivalent energy elastic plastic (EEEP), and hysteretic parameters of tested SCWF shear wall specimens. Experimental tests also provided the seismic design coefficients of SCWF shear walls, which are currently lacking in the building codes.

This book was released on 2006 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Methods for the design of steel frame/wood panel shear walls used as a seismic force resisting system have been developed. These methods, which can be used in conjunction with the 2005 NBCC, were based on the results of shear wall tests carried out using lateral loads alone. The research program was extended to determine the influence of gravity loads on the lateral performance of the shear wall. An initial series of stud column tests was completed to determine an appropriate predication method for the axial capacity of the principal vertical load carrying members. Recommendations for appropriate effective length factors and buckling lengths were derived from the results of 40 tests. A subsequent series of five single-storey shear wall configurations were designed using capacity based methods. These shear walls were tested under monotonic and cyclic lateral loading, where two of three shear walls were also subjected to a constant gravity load. In total, 32 steel frame/wood panel shear walls composed of 1.09--1.37 mm thick steel studs sheathed with DFP, CSP or OSB panels were tested and analyzed. The equivalent energy elastic-plastic analysis approach was used to determine design values for stiffness, strength, ductility and overstrength. The data from this most recent series of tests indicates that the additional gravity loads do not have a detrimental influence on the lateral behaviour of a steel frame/wood panel shear wall if the chord studs are designed to carry the combined lateral and gravity forces following a capacity based approach. A resistance factor of 0.7 was found to be in agreement with previous tests that did not include gravity loads. The calculated seismic force modification factors also agreed with the previous test results, which suggest that Rd = 2.5 and Ro = 1.7." --

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Canadian seismic design provisions for cold-formed steel framed/steel sheathed shear walls have been developed from previous research at McGill University with the intent of being incorporated into the Canadian section of the North American Lateral Design Standard for Cold-Formed Steel Framing (AISI S213), and ultimately to provide guidelines for design of these systems in the National Building Code of Canada and CSA-S136 Specification.In this previous research, a limited number of shear walls displayed unfavourable damage due to twisting deformations of the chord-studs and by local buckling. Also, the shear walls tested in previous research were only laterally loaded. The objective of the current research program was to address this unfavourable failure mode by evaluating the performance of cold-formed steel framed/steel sheathed shear walls, constructed with blocked stud members, which were tested under combined gravity and lateral loading. In total, fourteen single-storey shear walls (8 configurations) were subjected to monotonic and CUREE reversed cyclic lateral loading protocols. The Equivalent Energy Elastic-Plastic (EEEP) approach was used to analyse the test data and determine nominal shear resistance values. Relevant design parameters were determined: a resistance factor, phi, of 0.7, an overstrength value of 1.4, and ductility and overstrength seismic force modification factors (Rd = 2.0 and Ro = 1.3). Dynamic analysis of a two storey representative building model was carried out to validate the 'test-based' R-values following a methodology adopted from FEMA P695 to evaluate the seismic performance of a building system.The research program indicated that the blocking reinforcement detail had adequately resolved chord-stud twisting deformations and that the chord-studs, once designed to carry the combined gravity and lateral forces following a capacity based approach, would not fail thereby preventing any detrimental collapse of the framing system." --

Available in PDF, EPUB and Kindle. Book excerpt: "To enter into the construction market for mid-rise buildings, e.g. 5 to 8 storeys, the cold-formed steel (CFS) industry requires a solution to address the need to resist higher seismic shear forces. The proven performance of steel-sheathed shear walls is required to compete with hot-rolled steel lateral framing shear wall systems; i.e. all-steel shear wall configurations capable of carrying lateral loads in excess of 60 kN/m (4170 lb/ft). The American Iron and Steel Institute (AISI) developed a design standard for cold-formed steel lateral framing systems, i.e. the AISI S400-15. This standard contains design information for shear walls with shear resistance values up to 30 kN/m (2085 lb/ft). Various solutions exist to increase the shear resistance of a CFS framed shear wall to a level appropriate for mid-rise buildings. For example, in shear walls with sheathing placed on both sides of the wall, torsional loading on the framing members was avoided, and hence the shear resistance was significantly increased. However, the ductility of the walls was not improved compared to previously run tests due to the sheathing pulling over the screw fasteners.A configuration in which the sheathing is placed at the mid-line of the framing, denoted the “centre-sheathed” shear wall, was recently developed through a laboratory test program. These walls were configured to centrally confine the sheathing within the framing, which resulted in the removal of torsional forces on the chord studs and provided for a substantial increase in both shear resistance and ductility in comparison with walls having external sheathing on both sides. The initial test walls proved to have higher shear resistance, i.e. over four times that currently found in the AISI S400-15, and could maintain this resistance to drifts exceeding 6%. However, the high shear forces posed difficulties in designing the perimeter framing members and attachments to the foundation given that the structure is composed of CFS with a maximum thickness of 2.5 mm. This second laboratory-based study was conducted to configure centre-sheathed walls to attain intermediate shear resistances but maintain the ability to carry load at high drift levels. In addition, tests were carried out on the bare frame structure to identify the added shear capacity provided by the specially detailed CFS perimeter frame. Further, connection tests were completed to address the need to develop bearing design equations for the double shear 3-ply screw connections that connect the sheathing to the frame, which is not currently addressed in any design standard on cold-formed steel"--

This book was released on 2019 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents experimental investigations of the performance of cold-formed steel lateral force-resisting systems (CFS-LRFS) under combinations of simulated earthquake and fire loading. Three types of shear wall systems are investigated: gypsum-sheet steel composite panel sheathed walls, oriented strand board (OSB) sheathed walls, and steel strap braced walls. Twenty-two 2.7 m tall by 3.7 m long test specimens are subjected sequentially to combinations of mechanical (cyclic shear deformation) and thermal (fire) load. The mechanical loading setup and protocol are based on ASTM E2126 Method C (CUREE Basic Loading Protocol). Fire loads of varying intensity that represent the characteristics of actual fires are investigated. The work is a step toward developing fragility curves (representations of the probability of exceeding a given damage state as a function of an engineering demand parameter) for these systems and is essential for performance-based design for fire.
Download or read book Wood framed Shear Wall Construction written by Thor Matteson and published by Thor Matteson. This book was released on 2011 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-framed shear walls are a crucial part of modern residential and small commercial buildings. Shear walls resist wind and earthquake forces to protect buildings from collapse. This book explains the engineering principles involved with shear wall design and proper construction. It is written in non-technical language intended for carpenters and builders. The basic, unchanging physical principles are explained with illustrated examples. This guide goes into detail that no other book on the subject even approaches. Over 180 pages and 150 color photos and illustrations show actual construction conditions and examples of proper and improper installations. It is extensively indexed for quick reference to specific topics. A detailed two-page illustration shows many basic requirements in graphical format for easy guidance. Specific sections of the International Building Code and International Residential Code are referenced where appropriate. This edition includes a new chapter on earthquake strengthening methods for existing buildings. This chapter was itself expanded into a completely separate book (over 250 pages) titled "Earthquake Strengthening for Vulnerable Homes." The book is intended mostly for carpenters and builders, but engineers and building inspectors also find the information very useful. Engineers may learn methods to make their shear wall designs more efficient and effective. An extensive inspection checklist (over 70 items) is included. This checklist is the basis for Special Inspection Guidelines for Wood-Frame Construction, currently under development by the Structural Engineers Association of Northern California.
Download or read book Influence of Gypsum Panels on the Response of Cold formed Steel Framed Shear Walls written by Sophie Lu and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Gypsum panels can be used as structural elements in cold-formed steel (CFS) framed shear walls to resist in-plane lateral loads. More commonly, however, gypsum panels are specified to solely provide sound-proofing and fire resistance, and hence are not accounted for in the structural design. Research has shown that gypsum-sheathed walls can provide in-plane lateral resistance and stiffness regardless of whether the gypsum is intended to act as a structural or non-structural component. On the one hand, the additional lateral resistance provided by the gypsum can be beneficial since a more economical design can be achieved. On the other hand, if the gypsum panels are not taken into account in the design, the additional stiffness provided by the gypsum may lead to increased seismic loads on the building. Moreover, in the current AISI S213 and S400 North American Standards for the seismic design of CFS framed structures the design must follow a capacity-based approach in which the resistance of all the members in the lateral load carrying path is greater than the probable resistance of the fuse element(s) combined with the gravity loads. Thus, the unaccounted lateral resistance provided by the gypsum panels can increase the resistance of the fuse element(s) and lead to an unexpected and possibly non-ductile failure in the other members of the lateral load carrying path. In the AISI S213 and S400 Standards, values for the nominal resistance and overstrength factor of wood, steel and gypsum sheathed shear walls are given, but have a limited range of application (e.g. 12.5 mm thick gypsum). No recommendations are provided to take into account the influence of gypsum in strap-braced walls, or the effect on probable capacity forces. The first objective of this thesis is to conduct a test program in order to obtain design values with respect to the nominal and maximum in-plane shear resistances, as well as the stiffness, of 1-hour and 2-hour fire resistance rated gypsum-sheathed strap-braced shear walls, gypsum-sheathed shear walls and gypsum-sheathed gravity-carrying walls. The second objective is to create a numerical model representing the behaviour of the tested gypsum-sheathed walls. A total of 35 2.44 m x 1.22 m walls were sheathed with different configurations of 15.9 mm-thick gypsum panels and then tested under in-plane lateral loading. Nominal values to be used in the design of gypsum-sheathed walls were found as well as methods to predict the probable resistance of gypsum-sheathed walls for capacity-based design. Numerical models of the walls were obtained with OpenSees and can be used to incorporate the effect of gypsum panels on walls in a full building model." --
