Book excerpt: The purpose of this study is to model and analyze the nonplanar shear wall assemblies of shear wall-frame structures. Two three dimensional models, for open and closed section shear wall assemblies, are developed. These models are based on conventional wide column analogy, in which a planar shear wall is replaced by an idealized frame structure consisting of a column and rigid beams located at floor levels. The rigid diaphragm floor assumption, which is widely used in the analysis of multistorey building structures, is also taken into consideration. The connections of the rigid beams are released against torsion in the model proposed for open section shear walls. For modelling closed section shear walls, in addition to this the torsional stiffness of the wide columns are adjusted by using a series of equations. Several shear wall-frame systems having different shapes of nonplanar shear wall assemblies are analyzed by static lateral load, response spectrum and time history methods where the proposed methods are used. The results of these analyses are compared with the results obtained by using common shear wall modelling techniques.

This book was released on 1981 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a user's guide for CTABS80, a computer program for the linear three-dimensional structural analysis of multistory frame and shear wall buildings subjected to static or dynamic loadings. In CTABS80, the building is idealized as an assemblage of vertical independent frame and shear wall systems interconnected by horizontal floor diaphragms which are rigid in their own plane. The frame and shear wall systems must basically be of rectangular geometry (in elevation) with vertical columns (or piers) and horizontal beams (or spandrels). However, with special modeling techniques, very complex situations may be considered. A special shear panel element is developed to enable modeling of discontinuous shear walls and shear walls with arbitrary openings. A diagonal bracing element to model braced frames (X-braced, K-braced, or eccentrically braced systems) is also presented. The column, shear panel, and diagonal formulations include the effects of bending, axial, and shear deformations. Bending and shear deformations are also included in the beam formulation; however, the effects of axial deformations are neglected. The effects of the finite dimensions of the beams and columns on the stiffness of a frame or shear wall system are automatically included.

Available in PDF, EPUB and Kindle. Book excerpt: The structural analysis of multi-storey buildings can be carried out using discrete (computer-based) models or creating continuum models that lead to much simpler albeit normally approximate results. The book relies on the second approach and presents the theoretical background and the governing differential equations (for researchers) and simple closed-form solutions (for practicing structural engineers). The continuum models also help to understand how the stiffness and geometrical characteristics influence the three-dimensional behaviour of complex bracing systems. The back-of-the-envelop formulae for the maximum deflection and rotation, load shares, fundamental frequency and critical load facilitate quick global structural analysis for even large buildings. It is shown how the global critical load ratio can be used for monitoring the "health" of the structure acting as a performance indicator and "safety factor". Evaluating the results of over sixteen hundred calculations, the accuracy of the procedures is comprehensively demonstrated by comparing the discrete and continuum results. Nineteen worked examples illustrate the use of the methods, whose downloadable MathCad and Excel worksheets (www.crcpress.com/ 9780367350253) can also be used as templates for similar practical situations.

Available in PDF, EPUB and Kindle. Book excerpt: A computer analysis has been developed to predict the behavior of tall buildings subjected to lateral loads. The buildings considered are composed of shear walls and frames. Each shear wall-frame unit undergoes equal lateral deformations and the structure as a whole does not deform torsionally. The analysis is performed on a subassemblage consisting of a lumped shear wall system and a simple substitute frame. The load-deflection relationship for the structure is determined up to the ultimate load. The formation of plastic hinges in the substitute frame has been considered as well as the inelastic action of the wall. In addition, the secondary moments produced by the axial forces in the columns acting through the sway displacements of the structure are considered. The lumping procedure used to form the subassemblage is discussed and the analysis of the subassemblage in both the elastic and inelastic range, including the P-[delta] effect, is presented. The results of the analysis are compared with those obtained by other methods. The behavior of a shear wall-frame structure is discussed and illustrated by an example.

This book was released on 2014 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lateral Stiffness is one of the most important properties of a building which not only defines resistance to displacements under lateral loads but it can also have a great impact on natural period of a structure. Different stiffness values can ultimately affect the behavior of a structure under seismic loads and lateral forces that will be applied to it. In this study several parameters that can affect lateral stiffness of shear wall-frame buildings have been studied. At first, different configurations of shear walls in plan were analyzed in both medium rise and high rise buildings. In both cases, models with a central concrete core showed higher stiffness and smaller lateral displacements but at the same time, higher story forces were applied to the structure in seismic analysis. Cracking in shear walls is the other parameter considered in this study. Results indicate that cracked modification factors introduced in ACI can greatly impact the stiffness and other related properties of a building. A more precise approach is used to identify cracked elements based on finite element methods. Openings in shear walls have also been studied. Analysis results showed that in the case considered, openings with an area up to 10% of the wall did not have a significant influence on stiffness of the structure but higher opening ratios eventually resulted into severe loss of stiffness and large displacements. Stiffness of walls not parallel to direction of load is also investigated. Results indicate that even small angles between direction of load and shear wall can considerably reduce the stiffness of a structure in a specific direction. In the end, two parameters affecting flexural capacity of shear walls have been studied, vertical reinforcement and wall thickness. Even though an increase in each of the two parameters can be helpful, results show that each of them can increase flexural capacity of a section more efficiently under different conditions. Analysis in all of the models is performed by ETABS 2013. The intention is not to get involved in too many complex calculations, but rather compare the behavior of buildings in different conditions as a practical guide.

The buildings may be unsymmetrical and nonrectangular in plan. Torsional behavior and interstory compatibility are accurately reflected in the results.

Available in PDF, EPUB and Kindle. Book excerpt: A sound and more modern Eurocode-based approach to design is the global approach, where the structures are considered as whole units, rather than to use traditional element-based design procedures. Although large frameworks and even whole buildings are now routinely analysed using computer packages, structural engineers do not always understand complex three-dimensional behaviour and thus manipulate the stiffness and the location of the bracing units to achieve an optimum structural arrangement. This guide deals with two categories of multi-storey structures. It can be used for the plane stress, stability and frequency analysis of individual bracing units such as frameworks, coupled shear walls and cores. In addition, and perhaps more importantly, it can be used for the three dimensional stress, stability and frequency analysis of whole buildings consisting of such bracing units. The closed-form solutions in the book may also prove to be useful at the preliminary design stage when quick checks are needed with different structural arrangements. Their usefulness cannot be overemphasized for checking the results of a finite element (computer-based) analysis when the input procedure involves tens of thousands of items of data and where mishandling one item of data may have catastrophic consequences. In addition to the critical load, the fundamental frequency, the maximum stresses and the top deflection of frameworks, coupled shear walls, cores and their spatial assemblies, a very important new piece of information is the "safety factor" of the structure (either a single unit or a whole building), which also acts as the performance indicator of the structure. MathCAD worksheets can be downloaded from the book’s accompanying website.

Book excerpt: The objectives of this study are to use SAP2000 to investigate lateral load paths and system behavior in a modular, light-frame wood structure by investigating different foundation configurations and to further develop and validate existing modeling techniques of shear wall elements based on the Perforated Shear Wall Method. The modeling methods were validated using full-scale tests on sub-assemblies and rectangular and L-shaped houses by previous researchers. ASCE 7-10 main lateral-force-resisting system and components and cladding wind loads are applied in perpendicular directions to the exterior walls. The analysis is performed for a series of foundation types to examine the effects on overall and local behavior. The effectiveness of the different foundation schemes was evaluated. It was found that the racking shear stiffness calibration procedures implemented previously for light-framed construction are also applicable for light-frame, modular shear walls. Additionally, it was found that anchorage elongation substantially affects the racking shear stiffness of shear walls with aspect ratios within limits similar to those provided by the Special Design Provisions for Wind and Seismic Design Standards. For regularly-shaped modular structures, it was found that assuming tributary areas to resisting elements for lateral loads produced conservative demands when ignoring contributions from uplift pressures. Thousands of structures such as these are used throughout the United States in various applications. Consequently, with wind loads being a major contributor to annual structural damage of light-framed wood structures and a need for methods to sufficiently evaluate load paths, this study is an important development in the design of modular buildings and their acceptance by building code officials.
