Book excerpt: The self-centering steel plate shear wall (SC-SPSW) is a lateral force-resisting system that is capable of providing enhanced seismic performance, including recentering after an earthquake. The primary lateral strength of the SC-SPSW is provided by thin steel infill plates, referred to as web plates, that are connected to the beams and columns. During lateral sway, the web plate resists lateral load through the development of tension field action, and energy is dissipated through ductile yielding of the plate. Unlike conventional steel plate shear walls, the boundary frame in the SC-SPSW employs post-tensioned (PT) beam-to-column connections that are allowed to rock open during lateral sway. If properly designed, the PT connections eliminate damage in the boundary frame and provide restoring forces necessary to recentering the building during an earthquake, thus reducing post-earthquake downtime and repair costs. This research builds upon previous analytical and numerical proof-of-concept studies on SC-SPSWs. Experimental testing was conducted to better understand SC-SPSW behavior and seismic performance. The experimental program consisted of (1) a series of large-scale subassembly cyclic tests to evaluate the impact of various design parameters on SC-SPSW behavior and component demands and (2) full-scale two-story pseudo-dynamic tests to evaluate system performance at three different seismic hazard levels. These tests also investigated possible performance-enhancing variations in SC-SPSW design that were not considered in the previous proof-of-concept study. Post-tensioned column base connections were proposed to eliminate damage in the columns and provide additional recentering. SC-SPSWs with web plates that are only connected to the beams were proposed as a means of mitigating web plate tearing and reducing column demands. Methods for designing PT column base connections and SC-SPSWs with web plates connected to the beams only are presented. Numerical investigations were conducted to evaluate different methods of modeling web plate behavior in SC-SPSWs, ranging from the relatively simple tension-only strip model to the more complex shell element model. When used in cyclic or dynamic analyses, the tension-only strip model was found to significantly underestimate the energy dissipation provided by the web plate, while the shell element model was too computationally demanding for wide-spread implementation. Based on numerical and experimental observations, a modified tension-compression strip model was proposed to conservatively approximate the web plate unloading resistance and the additional energy dissipation it provides. Nonlinear response history analyses were conducted to asses seismic performance of several three- and nine-story SC-SPSW designs. These analyses compared SC-SPSWs with web plates connected to the beams and columns (fully-connected) and SC-SPSWs with web plates connected to the beams only (beam-connected). Results showed that SC-SPSWs using beam-connected web plates had smaller boundary frame members and larger drift demands than their fully-connected web plate counterparts; however, they were still able to meet proposed performance objectives. The numerical simulations also investigated the effects of considering the web plate unloading resistance in the model (e.g. the traditional tension-only model vs. the modified tension-compression model). These analyses showed that considering even small amounts of compression in the strip model significantly reduced drift demands.

Available in PDF, EPUB and Kindle. Book excerpt: Conventional lateral force resisting systems (LFRS) that comply with current building codes typically are designed for collapse prevention for a design level earthquake. Accordingly, significant structural damage is expected, leading to large residual drifts where yielded elements are difficult to repair or replace. Consequently, after a design level earthquake, demolition of the building may be required due to severe structural damage. An innovative self-centering steel plate shear wall (SC-SPSW) is proposed. The objective is to offer enhanced structural performance beyond conventional lateral systems by providing frame recentering and also to minimize structural damage of gravity frame components of the LFRS. The SC-SPSW combines the advantages of high initial stiffness and substantial energy dissipation provided by SPSW infill web plates, provides frame self-centering capability through the use of post-tensioned (PT) rocking frame joint connections, and concentrates hysteretic energy dissipation to replaceable infill web plates. In doing so, the SC-SPSW is intended to recover to its near pre-earthquake condition, after a moderate to significant earthquake, decreasing life-cycle costs. To investigate and validate the behavior of the SC-SPSW system, an experimental program of one-third scaled single-bay three-story frames was developed and conducted, consisting of quasi-static cyclic and dynamic shake-table testing. SC-SPSWs detailed with three different beam-to-column rocking joints were investigated. A final complementary test was performed at the National Center for Earthquake Engineering in Taiwan, where a full scale single-bay two-story specimen was subjected to an earthquake excitation loading using the pseudo-dynamic testing method. The experimental results show that SC-SPSWs systems can be a viable LFRS appropriate for buildings in regions of high seismicity. Furthermore, to assist in the design of SC-SPSWs, fundamental knowledge on the kinematics of SC-SPSWs through detailed free body diagrams are established, from which validated closed-form equations describing beam strength demands, tensile strain demands on the infill web plate, and unrestrained PT boundary frame expansion (aka beam-growth) of frames with PT rocking connections are provided in a form suitable for use as design tools.

Download or read book Steel Plate Shear Walls with Gravity Load Theory and Design written by Yang Lv and published by Springer Nature. This book was released on 2022-02-10 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written by subject experts based on the recent research results in steel plate shear walls considering the gravity load effect. It establishes a vertical stress distribution of the walls under compression and in-plane bending load and an inclination angle of the tensile field strip. The stress throughout the inclined tensile strip, as we consider the effect of the vertical stress distribution, is determined using the von Mises yield criterion. The shear strength is calculated by integrating the shear stress along the width. The proposed theoretical model is verified by tests and numerical simulations. Researchers, scientists and engineers in the field of structural engineering can benefit from the book. As such, this book provides valuable knowledge, useful methods, and practical algorithms that can be considered in practical design of building structures adopting a steel shear wall system.

Available in PDF, EPUB and Kindle. Book excerpt: Displacement-Based Seismic Design of Structures is a book primarily directed towards practicing structural designers who are interested in applying performance-based concepts to seismic design. Since much of the material presented in the book has not been published elsewhere, it will also be of considerable interest to researchers, and to graduate and upper-level undergraduate students of earthquake engineering who wish to develop a deeper understanding of how design can be used to control seismic response. The design philosophy is based on determination of the optimum structural strength to achieve a given performance limit state, related to a defined level of damage, under a specified level of seismic intensity. Emphasis is also placed on how this strength is distributed through the structure. This takes two forms: methods of structural analysis and capacity design. It is shown that equilibrium considerations frequently lead to a more advantageous distribution of strength than that resulting from stiffness considerations. Capacity design considerations have been re-examined, and new and more realistic design approaches are presented to insure against undesirable modes of inelastic deformation. The book considers a wide range of structural types, including separate chapters on frame buildings, wall buildings, dual wall/frame buildings, masonry buildings, timber structures, bridges, structures with isolation or added damping devices, and wharves. These are preceded by introductory chapters discussing conceptual problems with current force-based design, seismic input for displacement-based design, fundamentals of direct displacement-based design, and analytical tools appropriate for displacement-based design. The final two chapters adapt the principles of displacement-based seismic design to assessment of existing structures, and present the previously developed design information in the form of a draft building code. The text is illustrated by copious worked design examples (39 in all), and analysis aids are provided in the form of a CD containing three computer programs covering moment-curvature analysis (Cumbia), linear-element-based inelastic time-history analysis (Ruaumoko), and a general fibre-element dynamic analysis program (SeismoStruct). The design procedure developed in this book is based on a secant-stiffness (rather than initial stiffness) representation of structural response, using a level of damping equivalent to the combined effects of elastic and hysteretic damping. The approach has been fully verified by extensive inelastic time history analyses, which are extensively reported in the text. The design method is extremely simple to apply, and very successful in providing dependable and predictable seismic response.
