This book was released on 2013-01-01 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 69 illustrates and compares major buildings seismic codes applied in the different Continents, namely U.S., Japan, New Zealand, Europe, Canada, Chile and Mexico. Bulletin 69 was prepared by Task Group 7.6 of fib Commission 7, under the leadership of the late Professor Robert (Bob) Park which, in tandem with Professor Paulay, had developed in the seventies new fundamental design concepts, most notably capacity design approach and structural design for ductility, that had made the NZ seismic Code the most advanced one of the time. This new approach has highly influenced the development of Eurocode 8, to which Bob Park has significantly contributed. Bob Park was also well informed of the situation in Japan, USA, Canada and South America. Such a wide view is reflected in Bulletin 69 showing similarities and differences among the major seismic codes, accompanied as far as possible by comments, hopefully useful for fostering international harmonization. A comprehensive summary of the major codes is provided in the first chapter of the bulletin. All codes are separately presented according to a common framework: an introduction section, which describes the history, the philosophy, the process development, the performance-based criteria, the strength of materials and the incorporation of strength reduction factors of each code; a second section devoted to the demand side, which specify the seismic design actions and associated criteria of each code for areas of different seismicity and for structures with different ductility properties/requirements; a third section devoted to the capacity side, which describes the capacities of members and joints and associated criteria of each code, including member strengths in flexure, shear and bars anchorage, desirable hierarchies of strength attainment, deformation capacities of mechanisms of inelastic deformation, detailing of beams, columns and structural walls, detailing of beam-column joints for shear and the detailing of diaphragms. The second chapter is devoted to the comparison of the more significant issues dealt in the considered codes. This includes: seismic design actions and associated criteria, capacity design practice, beams, columns, confinement, structural walls and joints. It is felt that fib Bulletin 69 represents a useful, unique instrument for rapidly gaining an overview of the distinguishing features of the major world codes, under both their conceptual framework and application rules.

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.

Download or read book Seismic Performance Limitation of Slender Reinforced Concrete Structural Walls written by Christopher Segura and published by . This book was released on 2017 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a substantial amount of research on the seismic performance of reinforced concrete structural walls (shear walls), modern design provisions for mid-rise and high-rise shear wall buildings have been developed with the goal of achieving significant ductility in the event of strong earthquake ground shaking. Observations following recent earthquakes in Chile (2010) and New Zealand (2011) have demonstrated that shear wall buildings designed according to modern seismic design codes for tension-controlled action may be vulnerable to brittle compression failure. For walls designed to yield in compression, current reinforced concrete design standards in the United States (ACI 318-14) assume that ductility is ensured if code-prescribed confinement provisions are satisfied at wall boundaries; however, recent laboratory tests suggest that thin, code-compliant walls may be susceptible to compression failure prior to achieving the inelastic deformation capacity assumed by current U.S. design codes (i.e., ASCE 7-10, ASCE 41-13). Seven, approximately one-half scale, ACI 318-14 compliant wall specimens (designated WP1-WP7) were subjected to reversed cyclic lateral loads and constant axial load. The specimens represented approximately the bottom 1.5 stories of an eight story cantilever wall. The first phase of testing (WP1-WP4) was conducted to identify potential deficiencies in current provisions. Test variables for the phase 1 specimens included the configuration of boundary longitudinal reinforcement, quantity and arrangement of boundary transverse reinforcement, and compression depth (influence by axial load, quantity of longitudinal reinforcement, and wall cross-section). For the second phase of testing (WP5-WP7), walls were designed either with thicker cross-sections, improved boundary transverse reinforcement details (i.e., continuous transverse reinforcement detail rather than hoop and cross-tie detail), or both. Phase 2 specimens were constructed with improved web details whereby longitudinal reinforcement was placed inside of transverse reinforcement and, in some cases, cross-ties were used to provide lateral restraint to longitudinal reinforcement. Abrupt compression failures occurred at plastic rotations as low as 1.1% for the thinnest walls. Plastic rotations greater than 2.5% were observed for walls that were 25% and 50% thicker and/or constructed with more stringent confinement detailing than required by ACI 318-14. Based on experimental results, it is suggested to improve the deformation capacity of thin walls by avoiding the use of cross-tie confinement, and using overlapping hoops or continuous transverse reinforcement instead. Within the web region of walls, it is recommended to provide transverse reinforcement for web longitudinal reinforcement within the plastic hinge region. A lateral drift capacity prediction equation was developed in a displacement-based design format and was shown to agree with experimentally measured drift capacities for a small database of slender wall laboratory tests. It was demonstrated that, in addition to provided boundary transverse reinforcement, drift capacity of slender walls is most impacted by compression depth (c), wall thickness (b), and wall length (lw). Based on experimental data, drift capacities greater than 2% may be expected for code compliant walls designed such that c/b2.5, while drifts lower than 1% are expected when c/b5.0.

This book was released on 2015-11-18 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to serve as an essential reference to facilitate civil engineers involved in the design of new conventional (ordinary) reinforced concrete (R/C) buildings regulatedby the current European EC8 (EN 1998-1:2004) and EC2 (EN 1992-1-1:2004) codesof practice. The book provides unique step-by-step flowcharts which take the readerthrough all the required operations, calculations, and verification checks prescribed bythe EC8 provisions. These flowcharts are complemented by comprehensive discussionsand practical explanatory comments on critical aspects of the EC8 code-regulatedprocedure for the earthquake resistant design of R/C buildings. Further, detailedanalysis and design examples of typical multi-storey three-dimensional R/C buildingsare included to illustrate the required steps for achieving designs of real-life structures which comply with the current EC8 provisions. These examples can be readily used as verification tutorials to check the reliability of custom-made computer programs and of commercial Finite Element software developed/used for the design of earthquakeresistant R/C buildings complying with the EC8 (EN 1998-1:2004) code.This book will be of interest to practitioners working in consulting and designingengineering companies and to advanced undergraduate and postgraduate level civilengineering students attending courses and curricula in the earthquake resistant designof structures and/or undertaking pertinent design projects.
