Performance-Based Seismic Design of Structures

Book excerpt: Seismic design of structures is fast turning to performance-based design (PBD) from old codal force-based design (FBD) method. The aim of the book is to expose readers to the meaning and need of PBD, the evolution of PBD to date, its various forms and applications. Various design philosophies and procedures have been described including modelling aspects and hazard considerations backed by examples. Direct displacement-based design (DDBD) and Unified PBD (UPBD) of reinforced concrete (RC) frame buildings, RC dual systems, steel frame buildings and bridge piers have also been explained. The main features of this book are as follows: • Illustrates performance-based seismic design to achieve the design target by performance objective-oriented design procedure. • Covers modern design philosophies, modelling aspects, concepts in nonlinearities and use of supplemental damping devices. • Contains a chapter on seismic safety of nonstructural components. • Describes UPBD design procedure and examples of different structural systems. • Includes application and examples with reference to SAP2000 software. This book is aimed at graduate students, researchers and professionals in civil engineering, earthquake engineering and structural design.
