Samenvatting
Performance-based seismic design (PBSD) for bridges is a design process that links deci-sion making for facility design rationally and scientifically with seismic input, facility response, and potential facility damage. The goal of PBSD is to provide decision makers and stakeholders with data that will enable them to allocate resources for construction based on levels of desired seismic performance. PBSD is an advance over current prescrip-tive bridge design methodologies. This report summarizes the current state of knowledge and practice for PBSD.
