ƒ^ƒCƒgƒ‹i‰pjF RELIABILITY-BASED OPTIMAL DESIGN IN CONSIDERATION OF STRUCTURAL SYSTEM AND ITS APPLICATION TO EVALUATION OF SEISMIC PERFORMANCE OF RC BRIDGE PIERS
´˜^i‰pjF Performance-based design is set to replace conventional methodologies. In this paper, design flow charts capable of handling any arbitrary level of safety are formulated using reliability-based optimal design theory by taking the structural system into consideration. These charts are then applied to the seismic design of rigid-frame bridge piers and RC bridge piers (single-column types) designed according to the current code so as to examine their seismic performance. It is confirmed that (1) RC bridge piers can be designed with the prescribed reliability using the proposal method and (2) the safety of bridge piers designed according to the current code is not uniform.
