摘　　要：研究了填充现浇石膏对网格框架墙体抗震性能的影响。分别对1片填充现浇石膏的钢筋混凝土网格框架墙体(填充石膏网格框架墙体)和1片未填充石膏的钢筋混凝土网格框架墙体(空网格框架墙体)试件进行了低周反复水平荷载作用下的抗震性能试验。试验表明:空网格框架墙体和填充石膏网格框架墙体均具有良好的延性,与空网格框架墙体相比,填充现浇石膏显著提高了网格框架墙体的初始刚度和承载能力,其耗能能力更强,对抗震有利。The effect of filling cast-in-situ gypsum on the seismic performance of the gird fram wall was studied. The seismic performance tests on two pieces of reinforcecl concrete grid frame wall under low cyclic horizontal loadings were carried out, one piece called gypsum-filled grid frame wall and the other called empty grid frame wall without gypsum. The tests show that both the empty grid frame wall and gypsum-filled grid frame wall have well ductility. Compared with empty grid frame wall, the initial stiffness and bearing capacity of gypsum-filled grid frame wall are significantly improved, and it has better energy dissipation capacity which is benefit for the seismic performance.
