Reinforced concrete (R/C) is one of the main building materials used worldwide and an understanding of its structural performance under gravity and seismic loads albeit complex is crucial for the design of cost effective and safe buildings. Concrete Buildings in Seismic Regions comprehensively covers of all the analysis and design issues related to the design of reinforced concrete buildings under seismic action. It is suitable as a reference to the structural engineer dealing with specific problems during the design process and also for undergraduate and graduate structural concrete and earthquake engineering courses. This revised edition provides new and significantly developed coverage of seismic isolation and passive devices and coverage of recent code modifications as well as notes on future developments of standards. It retains an overview of structural dynamics the analysis and design of new R/C buildings in seismic regions post-earthquake damage evaluation pre-earthquake assessment of buildings and retrofitting procedures and several numerical examples. The book outlines appropriate structural systems for many types of buildings explores recent developments and covers the last two decades of analysis design and earthquake engineering. It specifically addresses seismic demand issues and the basic issues of structural dynamics considers the capacity of structural systems to withstand seismic effects in terms of strength and deformation and highlights the assessment of existing R/C buildings under seismic action. All of the material has been developed to fit a modern seismic code and offers in-depth knowledge of the background upon which the code rules are based. It complies with European Codes of Practice for R/C buildings in seismic regions and includes references to current American Standards for seismic design.
