Seismic Design of Concrete Buildings to Eurocode 8

An Original Source of Expressions and Tools for the Design of Concrete Elements with Eurocode Seismic design of concrete buildings needs to be performed to a strong and recognized standard. Eurocode 8 was introduced recently in the 30 countries belonging to CEN, as part of the suite of Structural Eurocodes, and it represents the first European Standard for seismic design. It is also having an impact on seismic design standards in countries outside Europe and will be applied there for the design of important facilities. This book: Contains the fundamentals of earthquakes and their effects at the ground level, as these are affected by local soil conditions, with particular reference to EC8 rules Provides guidance for the conceptual design of concrete buildings and their foundations for earthquake resistance Overviews and exemplifies linear and nonlinear seismic analysis of concrete buildings for design to EC8 and their modelling Presents the application of the design verifications, member dimensioning and detailing rules of EC8 for concrete buildings, including their foundations Serves as a commentary of the parts of EC8 relevant to concrete buildings and their foundations, supplementing them and explaining their proper application Seismic Design of Concrete Buildings to Eurocode 8 suits graduate or advanced undergraduate students, instructors running courses on seismic design and practicing engineers interested in the sound application of EC8 to concrete buildings. Alongside simpler examples for analysis and detailed design, it includes a comprehensive case study of the conceptual design, analysis and detailed design of a realistic building with six stories above grade and two basements, with a complete structural system of walls and frames. Homework problems are given at the end of some of the chapters.

Michael N. Fardis is professor and director of Structures Laboratory, Civil Engineering Department, University of Patras, Greece. He holds a MSc in civil engineering (1977) and nuclear engineering (1978), and a PhD in structural engineering (1979), all from the Massachusetts Institute of Technology (MIT). Fardis has written seven books, edited two books, and co-edited two more. He has also published more than 300 papers in international journals or conference proceedings. In addition, as chairman of the CEN Committee for Eurocode 8: ‘Design of Structures for Earthquake Resistance’ (1999–2005), he led the development of its six parts into European standards. Eduardo C. Carvalho graduated from the Technical University of Lisbon in 1974 as a civil engineer, obtained the specialist degree in structures by the National Laboratory for Civil Engineering (LNEC) in Lisbon in 1980, and was a principal researcher at LNEC for 30 years. He is currently the chairman of Gapres, a structural design office in Lisbon; the chairman of the CEN committee for Eurocode 8: ‘Design of Structures for Earthquake Resistance’ (CEN/TC250/SC8); chairs the Portuguese mirror group for the implementation of Eurocode 8 in Portugal; and is a member of the Technical Council of federation international du béton (fib). Peter Fajfar is a professor of structural and earthquake engineering at the Faculty of Civil and Geodetic Engineering, University of Ljubljana, Slovenia. He obtained his PhD from the University of Ljubljana (1974), and is the leader of the implementation process of Eurocode 8 in Slovenia, the first country to implement Eurocode 8. Fajfar has co-authored the first comprehensive book on earthquake engineering in former Yugoslavia, co-edited three books published by international publishers, and authored several books. In addition, he has also published more than 200 scientific papers in journals and conference proceedings, and participated in more than 100 design projects. Alain Pecker is the president of Géodynamique et Structure, and professor of civil engineering at Ecole des Ponts ParisTech in France. He holds a degree in civil engineering from Ecole des Ponts ParisTech and an MSc from the University of California at Berkeley. He is president of the French committee for the development of seismic design codes, was a member of the drafting panel of EN 1998-5, and has been a consultant to major civil engineering projects in seismic areas worldwide. He has also authored two books, co-authored three books, and presented 130 papers in international journals or conference proceedings.
