Nonlinear static monotonic (pushover) analysis has become a common practice for performance-based seismic bridge design. The popularity of pushover analysis is due to its ability to identify the failure modes and the design limit states of bridge piers and provide the progressive collapse sequence of damaged bridges when subjected to major earthquakes. Covering the simplest to the most sophisticated methods, this book includes step-by-step procedures for pushover analysis. The authors also provide a computer program, called INSTRUCT, that allows readers to perform their own analyses.
