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.

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.

The study focuses on the comparison of the American and Indian standards in relation to seismic design and analysis of reinforced concrete structures. Seismic provisions of the current versions of ASCE 7 and IS 1893 are compared on the basis of the type of allowable analysis procedures, zoning system, site classification, fundamental time period of the structure, response reduction factor, importance factor, minimum design lateral force, allowable story drifts, and design response spectra. Two geometrically similar commercial reinforced concrete buildings were designed in high seismic regions of USA and India as per the respective seismic provisions in ASCE 7 and IS 1893. The member dimensions, reinforcement sizes, and detailing were determined per guidelines of the respective codes.

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".
