纤维石膏填充墙-钢筋混凝土框架抗震性能试验研究
Experimental Study on the Seismic Behavior of RC Frame with Fiber Gypsum Infilled Wall
摘要
Abstract
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 RC seismic behavior,four one-bay and 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 the fiber gypsum infilling wall RC frame with rigid connections.Therefore,compared with the traditional masonry infilled wall,fiber gypsum infilled wall has a better practical value and application prospect in the actual engineering.关键词
