Book excerpt: The international seminar on Comparative Performances of Seismic Design Codes was the first opportunity for 'The Concrete Committee' of the Japan Society of Civil Engineers (JSCE) to organize an international event to disseminate its own research products and activities world wide. The topic of the seminar was selected following the 1996 publication of 'The Seismic Design Code' by 'The Concrete Committee' of JSCE. The damages suffered by modern concrete structures during the Hyogoken-Nanbu Earthquake in 1995 was the principal motivation for these revisions of the code. This presented an opportunity to try to compare the performance of the revised code with those of existing major seismic design codes in the world, i.e., CALTRANS Code, EURO Code 8, NEW ZEALAND Code. Due to the unique seminar format, Volume 1 of the proceedings introduced explanatory notes for the four codes. In addition, the four codes were applied to the comparative designs of bridge piers by 'The Committee on Comparative Design of Bridge Piers'. The outcome of this was remarkable, as shown in this work. Diversities to the designed sections according to the different codes were shown, even though the ground motions, mass of super structures and materials were the same throughout the designed bridge piers. Differences were particularly noted for high piers with large ground acceleration. In the seminar, fundamental reasons for these differences were discussed and numerical evaluations presented. Volume 1 was published prior to the seminar, Volume 2 was published after the seminar concluded. Volume 2 of the seminar proceedings includes the discussion for the contents of Volume 1 and the main elements of the four codes. Therefore, some of the modifications for the trial design of bridge piers in Volume 1, are also included reflecting the discussion at the seminar. Besides these, the contents include the numerical evaluation of designed bridge piers, which conclude the comparison of the performances of four major seismic design codes as a whole. As appendices, the main provisions of the four codes that are used in designing are attached so that the readers of the books will benefit from the convenience of the reference. The overall aim of the International Seminar on Comparative Performances of Seismic Design Codes for Concrete Structures are thus accomplished and we are quite sure that this will help structural engineers who are engaged in seismic design of RC structures to understand the differences of the basic ideas underlying in each of the seismic design code provisions with ease and to make most of those.

Download or read book Critical comparison of major seismic codes for buildings written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. 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 2009-07-25 with total page 757 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the historic first European seismic code, this professional book focuses on seismic design, assessment and retrofitting of concrete buildings, with thorough reference to, and application of, EN-Eurocode 8. Following the publication of EN-Eurocode 8 in 2004-05, 30 countries are now introducing this European standard for seismic design, for application in parallel with existing national standards (till March 2010) and exclusively after that. Eurocode 8 is also expected to influence standards in countries outside Europe, or at the least, to be applied there for important facilities. Owing to the increasing awareness of the threat posed by existing buildings substandard and deficient buildings and the lack of national or international standards for assessment and retrofitting, its impact in that field is expected to be major. Written by the lead person in the development of the EN-Eurocode 8, the present handbook explains the principles and rationale of seismic design according to modern codes and provides thorough guidance for the conceptual seismic design of concrete buildings and their foundations. It examines the experimental behaviour of concrete members under cyclic loading and modelling for design and analysis purposes; it develops the essentials of linear or nonlinear seismic analysis for the purposes of design, assessment and retrofitting (especially using Eurocode 8); and gives detailed guidance for modelling concrete buildings at the member and at the system level. Moreover, readers gain access to overviews of provisions of Eurocode 8, plus an understanding for them on the basis of the simple models of the element behaviour presented in the book. Also examined are the modern trends in performance- and displacement-based seismic assessment of existing buildings, comparing the relevant provisions of Eurocode 8 with those of new US prestandards, and details of the most common and popular seismic retrofitting techniques for concrete buildings and guidance for retrofitting strategies at the system level. Comprehensive walk-through examples of detailed design elucidate the application of Eurocode 8 to common situations in practical design. Examples and case studies of seismic assessment and retrofitting of a few real buildings are also presented. From the reviews: "This is a massive book that has no equal in the published literature, as far as the reviewer knows. It is dense and comprehensive and leaves nothing to chance. It is certainly taxing on the reader and the potential user, but without it, use of Eurocode 8 will be that much more difficult. In short, this is a must-read book for researchers and practitioners in Europe, and of use to readers outside of Europe too. This book will remain an indispensable backup to Eurocode 8 and its existing Designers’ Guide to EN 1998-1 and EN 1998-5 (published in 2005), for many years to come. Congratulations to the author for a very well planned scope and contents, and for a flawless execution of the plan". AMR S. ELNASHAI "The book is an impressive source of information to understand the response of reinforced concrete buildings under seismic loads with the ultimate goal of presenting and explaining the state of the art of seismic design. Underlying the contents of the book is the in-depth knowledge of the author in this field and in particular his extremely important contribution to the development of the European Design Standard EN 1998 - Eurocode 8: Design of structures for earthquake resistance. However, although Eurocode 8 is at the core of the book, many comparisons are made to other design practices, namely from the US and from Japan, thus enriching the contents and interest of the book".

Download or read book Displacement based Seismic Design of Reinforced Concrete Buildings written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. 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 2015 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, concrete Diagrids have been more widely used in the current Diagrid building designs, especially with mid-rise buildings. Looking through the entire portfolio of completed Diagrid structures, there are very few Diagrid tall building structures located in the area where seismic forces govern the lateral design. An investigation on the seismic performance of concrete Diagrid structures would give the engineers a better understanding of this unique type of structural system. A comparative research was conducted in this paper on the seismic performance of concrete Diagrid structures comparing to steel Diagrid structures. Two building height scenarios were considered for mid-rise 8-story buildings and high-rise 60-story buildings. Response spectrum analysis was used for two different earthquake locations corresponding to code based seismic design approach using ASCE 7-10. The seismic performances of both types of Diagrid structures were also compared to 8-story moment frame buildings and 60-story outrigger buildings for the two scenarios respectively. With all member sizes set to be fixed across all models, steel Diagrids were found to be performing better than concrete Diagrids in terms of natural period and controlling top drifts while concrete was tested to be better at controlling top accelerations. Comparing to outrigger and moment frame systems, both concrete and steel Diagrid structures were tested to be stiffer and more effective in restraining top drifts but less satisfying in limiting top accelerations.

Book excerpt: This report describes a recommended methodology for reliably quantifying building system performance and response parameters for use in seismic design. The recommended methodology (referred to herein as the Methodology) provides a rational basis for establishing global seismic performance factors (SPFs), including the response modification coefficient (R factor), the system overstrength factor, and deflection amplification factor (Cd), of new seismic-force-resisting systems proposed for inclusion in model building codes. The purpose of this Methodology is to provide a rational basis for determining building seismic performance factors that, when properly implemented in the seismic design process, will result in equivalent safety against collapse in an earthquake, comparable to the inherent safety against collapse intended by current seismic codes, for buildings with different seismic-force-resisting systems.

This book was released on 1998-04-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This detailed guide will enable the reader to understand the relative importance of the numerous parameters involved in seismic design and the relationships between them, as well as the motivations behind the choices adopted by the codes. For a structure to remain elastic under its design seismic action, typically associated with a 10% exceedance probability in 50 years, it has to be designed for lateral forces with magnitude in the order of 50% or more of its weight. Although technically feasible, designing a structure to respond elastically to its design seismic action is economically prohibitive. It is also completely unnecessary, as the earthquake is a dynamic action, representing for a structure a certain total energy input and a demand to tolerate a certain level of displacement and deformation, but not a demand to withstand specific forces. Therefore, seismic design codes allow the development of significant inelastic response under the design seismic action, provided that the magnitude of inelastic deformations does not endanger the integrity of the individual members and of the structure as a whole. The rapid development which has occurred in seismic codes has left a need to review the theoretical framework underlying the process of modern seismic design of reinforced concrete, if for no other reason than to make it more accessible and to explain its logic to those outside the small circle of experts. This design guide aims to satisfy this need in a pragmatic way. The book begins by outlining, comparing and contrasting the approaches taken by four regional codes (New Zealand, USA, Europe and Japan). Next follows a chapter on reliability-based system analysis which demonstrates that the problem of seismic design can be theoretically formulated in a comprehensive way which can provide results of practical value. The main part of the guide is devoted to practical issues relating to the measurement of seismic performance and case reports. The detailed discussions provided will enable the interested reader to understand the relative importance of the numerous parameters involved in seismic design and the relationships between them, as well as the motivations behind the choices adopted by the codes. The final chapter on the assessment of existing buildings covers a crucial topic for the future of earthquake engineering.
