Newly Development of Performance-Based Seismic Design of Bridges in Taiwan

This study presents the “Draft of the Performance-Based of Seismic Design Specification for Highway Bridges”. This draft specification includes:: General requirement, Seismic performance requirement, Seismic hazard and demand, The first-stage design, The second-stage verification of seismic performance, Ductile design of reinforcement concrete structure, Ductile design of steel structure, Foundation and abutment, Isolation and energy dissipation, and Other consideration. Compared to the current Seismic Design Specification for Highway Bridges(2009), this draft specification precisely defines a performance matrix, and allows the engineer to have more flexibility when conducting preliminary design.However, it emphasizes more on the performance evaluation to satisfy the basic requirement of structural safety, service ability and reparability.
