【摘要】Fiber gypsum composite material has good physical and mechanical properties,but the study of using it as infilled wall materials is less.To study the seismic behavior of fiber gypsum infilled wall RC frame and the effects of constructional details of infilling wall have on the

one-bay

one-story

specimens,including one bare frame without infilling walls,one shale brick infilling wall with rigid connection to RC frame,two fiber gypsum infilling walls,where one fiber gypsum wall was with flexible connections and another with rigid connection,were designed with half-scale and tested under low-cycle reversed loads.The damage behavior,hysteresis curves,skeleton

curves,stiffness

degradation,bearing

capacity,deformation capacity and energy-dissipation capacity of the specimens were analyzed.The results showed that the infilling wall could improve the bearing capacity and energy-dissipation capacity of the frame structure.Compared with traditional RC frame with shale brick infilling wall,the RC frames with fiber gypsum infilled wall has a better bearing capacity and deformation capacity.The fiber gypsum infilling wall RC frame with flexible connections has a better seismic behavior to
