A displacement-based method of seismic design (DBSD) is presented with particular reference to the design of reinforced concrete shear wall buildings. For preliminary design, approximate estimates of the yield and ultimate displacements are obtained, the former from simple empirical relations, and the latter to satisfy the following criteria: (1) satisfy code-specified drift limits, (2) ensure stability under P-Delta effects, and (3) keep the ductility demand within ductility capacity. For a multi-storey building the structure is converted to an equivalent single-degree-of-freedom (SDOF) system using an assumed deformation shape that is representative of the first mode. The required base shear strength of the SDOF system is determined from the inelastic demand spectrum corresponding to the ductility demand, which is the ratio of ultimate to yield displacement. The base shear is distributed across the height using an assumed pattern, such as the one given by the National Building Code of Canada, and the structure is designed for the moments produced by the estimated shears.

In order to allow the formation of the greatest number of plastic hinges and to dissipate as much as possible seismic energy of moment-resisting frames, dissipative zones should be mainly located in plastic hinges in the beams or in the beam-column joints, but not in the columns except at the base of the frame. It is clear that this design method strongly depends on actual mechanical properties of materials. The possibility that the actual yield strength of steel is higher than the nominal yield strength in dissipative zones should be taken into account by a material overstrength factor for the design of non-dissipative zones. In spite of the fact that this point is essential in seismic design, the value to be given to this overstrength factor varies in the provisions of different standards. Moreover, these standards don't provide adequate limitations on mechanical properties for steel products even if it should be directly related to the overstrength factor chosen. For these reasons, this work aimed to define suitable harmonised rules and recommendations for production standards and structural regulations for steel-concrete composite structures located at earthquake-prone areas.

Capacity-Demand Index Relationships for Seismic Design
Kenneth Farrow
Publisher VDM Verlag, 2009
ISBN 3639180259, 9783639180251
Length 296 pages
Seismic design procedures in current building provisions are based on linear and nonlinear static approaches that use capacity-demand index relationships such as the relationship between the lateral strength and the maximum lateral displacement. Previous research on the development of these relationships is based on linear-elastic ground motion acceleration response spectra, whereas the current design procedures are based on "smooth" design response spectra. For the design procedures to be consistent, new capacity-demand index relationships are proposed based on smooth design response spectra from existing design provisions. This book provides procedures that utilize these capacity-demand index relationships for the purpose of producing viable structural designs using performance-based engineering concepts (e.g., inelastic capacity-demand spectra methods). The tools herein summarize the basic understanding of seismic design essential for any practicing structural engineer.

he technique of plastic design has many advantages over the traditional elastic design technique. The methodology was developed in large part by M. R. Horne and his co-workers, and first came into wide-spread practical application in Britain. With the publication of this book, American designers and engineers will be given easy access to the latest developments in the theory and practice of plastic design.The advantages of this technique for simple beam systems and single-story buildings are considerable: plastic design represents a more rational approach and the analysis can be accomplished quickly and directly, and it facilitates economies in the use of materials. Moreover, the methods can be readily extended to buildings that are several stories (four or five) high.The first chapter reviews the fundamental methods of plastic analysis. Following chapters take up such topics as plastic moment distribution, modifying factors in plastic bending, frame stability and deflections (including the destabilizing effects of column axial loads on frames), the rigid-plastic behavior of a frame, and the elastic-plastic behavior of frames. A final chapter explains various practical considerations, such as joint design and the stiffening effects of cladding. All the chapters are linked so that the flow of the presentation is even throughout.The book considers whole structures as well as the behavior of various elements. Numerous worked examples are presented, some of which are taken from actual designs.M. R. Horne is Beyer Professor of Civil Engineering at the University of Manchester and author of Plastic Theory of Structures. L. J. Morris is a senior lecturer on the Manchester civil engineering faculty. The book is the second in the MIT Press Series in Structural Mechanics, edited by H. Max Irvine.

The unstiffened steel plate shear wall (SPSW) system has emerged as a promising lateral load resisting system in recent years. However, seismic code provisions for these systems are still based on elastic force-based design methodologies. Considering the ever-increasing demands of efficient and reliable design procedures, a shift towards performance-based seismic design (PBSD) procedure is proposed in this work. The proposed PBSD procedure for SPSW systems is based on a target inelastic drift and pre-selected yield mechanism. This design procedure is simple, yet it aims at an advanced design criterion. The proposed procedure is tested on a four-story test building with different steel panel aspect ratios for different target drifts under selected strong motion scenarios. The designs are checked under the selected ground motion scenarios through nonlinear response-history analyses. The actual inelastic drift demands are found to be close to the selected target drifts. In addition, the displacement profiles at peak responses are also compared with the selected yield mechanism.
