This book was released on 2003 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief summary of the history of seismic design as given in chapter 1, indicates that initially design was purely based on strength or force considerations. When the importance of displacement, however, became better appreciated, it was attempted to modify the existing force-based approach in order to include considerations of displacement, rather than to totally reconsider the procedure on a more rational basis. In the last decade, then, several researchers started pointing out this inconsistency, proposing displacement-based approaches for earthquake engineering evaluation and design, with the aim of providing improved reliability in the engineering process by more directly relating computed response and expected structural performance. The main objective of this report is to summarize, critically review and compare the displacement - based approaches proposed in the literature, thus favouring code implementation and practical use of rational and reliable methods. Chapter 2 Seismic performance and design objectives of this report introduces concepts of performance levels, seismic hazard representation, and the coupling of performance and hazard to define performance objectives. In fact, for displacement analysis to be relevant in the context of performance-based design, the structural engineer must select appropriate performance levels and seismic loadings. A critical review of some engineering limit states appropriate to the different performance levels is therefore proposed. In chapter 3 Conceptual basis for displacement-based earthquake resistant design, the fundamental principles associated with displacement of the ground during an earthquake and the effects, in terms of displacement, in the structure, are reviewed. The historical development guides the presentation with a review of general linear and nonlinear structural dynamics principles, general approaches to estimate displacement, for both ground and structure, and finally a general presentation of the means to measure and judge the appropriateness of the displacements of the structure in section. Chapter 4 Approaches and procedures for displacement-based design can be somehow considered the fundamental part of the report, since a critical summary of the displacement - based approaches proposed by different researchers is presented there. Displacement - based design may require specific characterization of the input ground motion, a topic addressed in Chapter 5 Seismic input. In general, various pertinent definitions of input motion for non-code format analysis are included, while peak ground parameters necessary for code base shear equations are only addressed as needed for the definition of motion for analysis. Chapter 6 Displacement capacity of members and systems addresses the fundamental problem of evaluating the inelastic displacement capacity of reinforced concrete members and realistic values of their effective cracked stiffness at yielding, including effects of shear and inclined cracking, anchorage slip, bar buckling and of load cycling. In Chapter 7 Application and evaluation of displacement-based approaches, some of the many different displacement based design procedures briefly introduced in Chapter 4 are applied to various case studies, identifying and discussing the difficulties a designer may encounter when trying to use displacement based design. Results for five different case studies designed in accordance with eight different displacement based design methods are presented. Although in general case studies are considered a useful but marginal part of a state of the art document, in this case it has to be noted that chapter 7 is possibly the most innovative and fundamental part of the whole report. The conclusions of chapter 7 are the fundamental and essential conclusions of the document and allow foreseeing a bright future for displacement - based design approaches. The state-of-art report has been elaborated over a period of 4 years by Task Group 7.2 Displacement-based design and assessment of fib Commission 7Seismic design, a truly international team of experts, representing the expertise and experience of all the important seismic regions of the world. In October 2002 the final draft of the Bulletin was presented to the public during the 1st fibCongress in Osaka. It was also there that it was approved by fib Commission 7Seismic Design.

This book was released on 2020 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete structural walls are frequently used as a lateral load resisting system in buildings. In some buildings affected by relatively recent seismic events, the response of the structural walls, traditionally labeled as excellent, has been somewhat unexpected and deserves attention.This dissertation focuses on enhanced numerical methodologies for the verification of the seismic response, including softening, of reinforced concrete structural wall systems. First, a Truss Model for reinforced concrete coupled structural walls is developed. Bar bond-slip, dowel action, and confining effect of the foundation are considered. Two cyclic tests, on scaled seven-story coupled walls (from literature), are used for validation. It is shown that the compressed wall piers resist most of the base shear force and that the coupling beams at lower levels develop the largest shear forces. Second, using the same benchmark test specimens, two models for the nonlinear cyclic analysis of reinforced concrete coupled walls are developed, i.e., Modified Beam-Truss Model and Enhanced Beam-Truss Model. The role of the strain penetration in diagonally reinforced coupling beams on the hysteretic energy dissipated is studied. It is verified that the computational-efficient proposed models predict well the overall response and the sliding shear failures of coupling beams. Third, the Beam-Truss Model developed in a previous study for the nonlinear cyclic analysis of reinforced concrete components is extended to compute out-of-plane buckling in structural walls. The novel Beam-Truss Model computes accurately the force-displacement responses and the buckling behavior of three test specimens reported in literature used for validation. Finally, the Beam-Truss Model is enhanced to compute the out-of-plane nonlinear shear response of wall piers in the analysis of Core-Wall-Building systems. Using the proposed model and pushover analyses, a comprehensive study on a 14-story archetype Core-Wall building is carried out. It is shown that the in-plane shear response has a large influence on the lateral strength and displacement capacity, whereas the out-of-plane shear response mainly influences the displacement capacity.

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.
