The DSDM (Diaphragm Seismic Design Methodology) Consortium is conducting a research project on precast concrete diaphragms. The project aims at developing an industry-endorsed comprehensive seismic design methodology for precast/prestressed concrete floor diaphragms. The methodology will aim to satisfy design requirements at three levels within the structure: the diaphragm level, the joint level, and the detail level. A desirable inelastic mechanism is achieved when the seismic input level exceeds the DBE level by using capacity design concepts to produce a hierarchy of design strengths at the joint and detail level.
