RECENT DEVELOPMENTS IN PERFORMANCE-BASED SEISMIC DESIGN OF BRIDGES
A recently completed research project on displacement-based seismic design of structures has included emphasis on bridge design. This paper summarizes the work carried out in this project. A brief discussion of conceptual problems with force-based seismic design of concrete bridges is followed by a description of displacement-based seismic design fundamentals. Seismic input for displacement-based design is briefly discussed, leading to examination of characteristics of bridges which could be expected to respond elastically to the design-level seismic input. Methodologies for longitudinal and transverse seismic design of irregular multi-span bridges are presented, and a brief discussion of capacity-design effects for bridges is included.
