Seismic Design of Rigid Wall-Flexible Diaphragm Buildings: An Alternate Procedure (FEMA P-1026)

This resource evaluates an alternative seismic design procedure for rigid wall-flexible diaphragm buildings, focusing on wood diaphragms and extending to bare steel deck roof diaphragms with special seismic detailing. It covers collapse margin parameters, acceptance criteria, performance groups, cyclic connector testing, diaphragm strength, ductility assessment, and 3D modeling for seismic performance. Appendices address updated design procedures and resolutions to concerns from previous versions.
