Performance Based Seismic Design
نویسنده
چکیده
Performance based seismic design (PBSD) is a cogent design approach that allows engineers to design structures with a predictable seismic performance for a specified level of hazard. In contrast to the conventional limit state or strength and serviceability based design in which a structure is designed to withstand severe load combinations and be functional under normal load conditions, PBSD goes beyond just safety and serviceability and addresses different structural performance expectations under various hazard levels. An important component of PBSD is the selection of a design criterion stated in the form of one or more performance objectives. A performance objective specifies a desired seismic performance level for a structure. Based on the Applied Technology Council report (https://www.scribd.com/doc/ 37801847/ATC-40), typical performance levels can be defined as follows:

A dual structural fused system consists of replaceable ductile elements (fuses) that sustain major seismic damage and leave the primary structure (PS) virtually undamaged. The seismic performance of a fused structural system is determined by the combined behavior of the individual PS and fuse components. In order to design a feasible and economic structural fuse concept, we need a procedure to ...
