A comprehensive experimental, analytical, and parametric investigation of the performance of gypsum-roof structures under severe earthquake excitations is presented. Force-deformation hysteresis were obtained from laboratory tests of typical gypsum panels to characterize the cyclic behavior of gypsum. The tests were also used to distinguish two levels of seismic performance: damage control and life safety. A special hysteretic model was developed to model the degrading behavior of the gypsum diaphragm. The model was incorporated into a special-purpose computer program with the ability to model inelastic in-plane diaphragm flexibility. The program was used to perform complete stiffness-degrading inelastic analysis of typical gypsum-roof structures subjected to a variety of accelerograms. The ensuing parametric study was directed at identifying a damage-based criteria for both the design of new structures and the retrofit of existing structures.
