This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various structural forms commonly adopted for the construction of multi-storey structures are outlined and the advantages of the use of shear walls as the load bearing elements in such structures are indicated. It is shown that, although a considerable amount of research has been devoted to the analysis of multi-storey structures, very little attention has been paid to the effects of foundation deformations on these structures. Three methods for the analysis of shear wall structures are indicated and the suitability of the continuous connection technique for the investigation of the effects of foundation deformations is shown. Two-dimensional coupled shear wall systems and single walls or box cores, all of which may be based on elastic foundations are analysed subjected to either of two generalised distributions of horizontal forces. The expressions derived for plane coupled shear walls are adapted to produce methods whereby design curves may be drawn for the rapid evaluation of stresses and deflections. The relationships derived for the two-dimensional analysis are used to derive a method for the analysis of the load distribution in three-dimensional multi-storey shear wall structures subjected to any system of lateral loads which may produce bending and torsion of the structure. The suitability of the analytical methods for the numerical computation of problems involving shear wall structures is discussed with particular reference to the feasibility of hand calculations and the development of a useful system of programs for computer analysis. The results of a number of numerical studies, carried out with the aid of the computer programs, are given to illustrate various aspects of the theory. The importance of accurately determining the extent and nature of the lateral load bearing systems within a structure is illustrated. The convergence of solutions obtained using the two load distributions are compared and the applications of each are discussed. The effects of varying the flexibility of the foundations, both of a two-dimensional coupled wall system and of specific walls in three-dimensional structures are illustrated by examples. A description is given of an experimental investigation carried out to study the effects of the elastic deformation of foundations on model shear wall structures constructed from "Perspex" sheets. The results of a comprehensive series of tests on the models are compared with the corresponding analytical solutions in order to assess the validity of the assumptions which were made in the derivation of the analytical methods.

Available in PDF, EPUB and Kindle. Book excerpt: The continuous medium analyses of two- and three-dimensional multi-storey shear wall structures are presented in this thesis. The system of planar coupled walls with continuously variable stiffness has been analysed and two methods of solution, the Galerkin and the finite difference methodsy proposed. The results of tests on perspex models with tapered width agreed reasonably well with the analytical results. A new technique which enables important design quantities for uniform coupled wall systems on flexible bases to be evaluated rapidly has been developed. The desIgn curves for several standard load cases, vertical and lateral loads have been produced. These design curves are applicable to two coupled wall systems or any symmetrical system with three coupled walls. The lateral-load analysis of symmetrical shear wall and shear wall-frame structures has been presented. The bending and torsional actions of the applied loads are analysed separately. Each separate analysis is reducible to the analysis of an equivalent analogous plane system. The method is particularly suitable for analysing a symmetrical structure which consists of a few distinct groups of coupled wall assemblies. Asymmetrical shear wall and shear wall-frame structures have also been treated, Finally the structure composed of thin-walled assemblies has been analysed by using Vlasov's theory for thin-walled beams of open section. The theoretical results were compared with the results of tests on a fourteen-storey perspex model. Reasonable agreement was obtained between theory and experiment.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, a rapid increase has taken place in the number of tall buildings. In multi-storey buildings made of reinforced concrete, the lateral loads are often resisted by specially arranged shear walls. Weakening of shear walls in tall buildings by doors, windows and corridor openings is one of the most frequently encountered problems of structural engineering. In planar coupled shear wall analyses, the lateral loads are applied in such a way that the deformation of the shear wall is confined within its own plane. In this book, the Continous Connection Method (CCM) is used in conjunction with Vlasov's theory of thin-walled beams, for the three dimensional analysis of non-planar coupled shear walls subjected to lateral loads which produce combined flexural and torsional deformations. To be more general, the present book deals with non-symmetrical structures both in the formulation and in the numerical applications. Both symmetrical and asymmetrical examples have been solved by the program prepared in the present study and compared with the solutions found by the SAP2000 structural analysis program and a perfect match has been observed.

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.

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 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.

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.
