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-place gypsum on the seismic performance of grid frame wall was studied. A piece of cast-in-place gypsum reinforced concrete grid frame wall (filled gypsum grid frame wall) and a piece of unfilled gypsum reinforced concrete grid frame wall (empty grid frame wall) specimens were Seismic behavior test under low cyclic repeated horizontal load. The results show that both the hollow grid frame wall and the filled gypsum grid frame wall have good ductility. Compared with the hollow grid frame wall, the cast-in-place gypsum significantly improves the initial stiffness and bearing capacity of the grid frame wall Ability, its energy-consuming ability is stronger, good for the earthquake.
