This book was released on 2014 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupled core wall systems with steel coupling beams are effective seismic force resisting systems to resist structural collapse. A typical coupling beam shear wall system would dissipate energy through the formation of plastic hinges at the coupling beam-wall interface. These plastic hinges would damage the coupling beam, requiring an infeasible and uneconomical repair involving the replacement of the beam embedded in the concrete wall pier. However, research at the University of Cincinnati has introduced a weak-link section (the fuse) at the mid-span of the coupling beam that will dissipate energy through shear yielding, leading to the development and modification of the steel fuse coupling beams. This would allow the plasticity at the face of the wall to be shifted to the mid-span of the coupling beam, requiring a feasible and economical repair involving only the replacement of the fuse at mid-span.

Available in PDF, EPUB and Kindle. Book excerpt: Following the 2010/2011 Canterbury Earthquakes, an investigation by the Canterbury Earthquakes Royal Commission (CERC) considered the performance of a range of buildings in Christchurch. Several of the buildings investigated by the CERC included reinforced concrete coupled walls, which are comprised of two wall piers linked (or coupled) by a series of coupling beams at each floor level. Notably the coupled wall buildings investigated by the CERC were observed to have performed undesirably when compared to their design intent. It was found by the CERC that these coupled walls tended to display higher strengths and lower ductility capacity than was intended in design. The postulated reason for this behaviour was that interaction between structural components strengthened the coupling beams by restraining the tendency of the coupling beams to axially elongate. To better account for this interaction in design practice, it was recommended by the CERC that the behaviour of coupled walls be investigated further. In this study, structural interaction between coupling beams and floors was first considered using finite element software VecTor2. It was found that the floors tended to restrain the elongation of coupling beams and to cause large coupling beam strength increases. The extent of floor that was activated to restrain coupling beam elongation being found to be dependent upon the arrangement of the floor. Existing provisions of NZS 3101:2006 for upper bounds on floor effective widths were found to be valid for assessment of the maximum coupling beam strength amplification caused by floor interaction. Analysis of a series of seismically loaded coupled walls interacting with floors was undertaken using VecTor2 software. In agreement with the findings of the CERC, axial restraint of coupling beams was found to have a large impact on coupled wall performance. Coupling beam strengths were measured up to 300% of their design strength, which tended to change the strength hierarchy of the coupled wall. In particular it was found that many existing coupled walls would have behaved similarly to a single cantilever wall with penetrations because the coupling beams were too strong to yield. These coupled walls tended to display lower energy dissipation and higher wall pier damage than assumed in design. The coupled wall provisions proposed (at the time of writing) in the 2014/2015 NZS 3101:2006 Amendment were found to over-estimate the impact of the floor systems on restraining coupling beam elongation. However these provisions did not include the effect of the wall piers restraining coupling beam elongation, so overall coupled wall overstrength capacities tended to be under-predicted. As an approximate method of accounting for axial restraint in design of coupled walls, it was recommended that redistribution of design demands be used to reduce the coupling beam design capacity and to achieve a more desirable coupled wall behaviour.

Available in PDF, EPUB and Kindle. Book excerpt: Performance-Based Seismic Design (PBSD) is a structural design methodology that has become more common in urban centers around the world, particularly for the design of high-rise buildings. The primary benefit of PBSD is that it substantiates exceptions to prescribed code requirements, such as height limits applied to specific structural systems, and allows project teams to demonstrate higher performance levels for structures during a seismic event.However, the methodology also involves significantly more effort in the analysis and design stages, with verification of building performance required at multiple seismic demand levels using Nonlinear Response History Analysis (NRHA). The design process also requires substantial knowledge of overall building performance and analytical modeling, in order to proportion and detail structural systems to meet specific performance objectives.This CTBUH Technical Guide provides structural engineers, developers, and contractors with a general understanding of the PBSD process by presenting case studies that demonstrate the issues commonly encountered when using the methodology, along with their corresponding solutions. The guide also provides references to the latest industry guidelines, as applied in the western United States, with the goal of disseminating these methods to an international audience for the advancement and expansion of PBSD principles worldwide.

Download or read book Displacement based Seismic Design of Structures written by M. J. N. Priestley and published by Iuss Press. This book was released on 2007 with total page 750 pages. 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.

Download or read book Seismic Design of Buildings to Eurocode 8 written by Ahmed Elghazouli and published by CRC Press. This book was released on 2016-12-19 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the seismic design of building structures and their foundations to Eurocode 8. It covers the principles of seismic design in a clear but brief manner and then links these concepts to the provisions of Eurocode 8. It addresses the fundamental concepts related to seismic hazard, ground motion models, basic dynamics, seismic analysis, siting considerations, structural layout, and design philosophies, then leads to the specifics of Eurocode 8. Code procedures are applied with the aid of walk-through design examples which, where possible, deal with a common case study in most chapters. As well as an update throughout, this second edition incorporates three new and topical chapters dedicated to specific seismic design aspects of timber buildings and masonry structures, as well as base-isolation and supplemental damping. There is renewed interest in the use of sustainable timber buildings, and masonry structures still represent a popular choice in many areas. Moreover, seismic isolation and supplemental damping can offer low-damage solutions which are being increasingly considered in practice. The book stems primarily from practical short courses on seismic design which have been run over a number of years and through the development Eurocode 8. The contributors to this book are either specialist academics with significant consulting experience in seismic design, or leading practitioners who are actively engaged in large projects in seismic areas. This experience has provided significant insight into important areas in which guidance is required.
