This Handbook is divided into four volumes, namely:

•Superstructure Design

•Substructure Design

•Seismic Design

•Construction and Maintenance

This volume, Seismic Design, provides the geotechnical earthquake considerations, earthquake damage, dynamic analysis and nonlinear analysis, design philosophies and performance-based design criteria, seismic design of concrete and steel bridges, seismic isolation and energy dissipation, active control, soil-structure-foundation interactions, and seismic retrofit technology and practice.
