玻化微珠保温混凝土空心剪力墙抗震性能研究

Study on seismic performance of glazed hollow bead insulation concrete hollow shear wall

玻化微珠保温混凝土空心剪力墙能够起到保温、隔热、隔音、减少混凝土用量、提高墙体变形和耗能能力等作用,具有显著的经济效益和社会效益。为研究玻化微珠保温混凝土空心剪力墙的抗震性能,制作了3个玻化微珠保温混凝土空心剪力墙试件,剪跨比分别为1.05、1.47、2.05,并对其进行水平低周往复荷载试验,同时利用ABAQUS软件进行数值模拟分析并进行承载力计算分析,研究得出试件承载力、滞回曲线、延性和耗能能力等性能指标。研究表明,普通剪力墙与玻化微珠保温混凝土空心剪力墙的受力机理相同,抗震性能相当,且提高剪跨比能够改善剪力墙的变形和耗能能力,但承载力有所下降。

Glazed hollow bead insulation concrete hollow shear wall have capacity of heat preservation,heat insulation,sound insulation,reduce concrete consumption,improve the wall deformation and energy dissipation,etc,it has significant economic and social benefits.In order to understand the seismic performance of glazed hollow bead insulation concrete hollow shear wall,low cycle loading tests of three shear walls with shear span ratio of 1.05,1.47,2.05.At the same time,using ABAQUS software for glazed hollow bead insulation concrete hollow shear wall analysis of numerical simulation and analysis of bearing capacity calculation,were carried out to study the bearing capacity,ductility performance and hysteretic curve.The results show the stress mechanism and seismic performance of hollow shear wall and ordinary shear wall are basically identical,and improving the shear span ratio improve the deformation and energy dissipation capacity of the shear wall,but bearing capacity declined.
