摘　　要：对玻化微珠再生保温混凝土剪力墙进行了低周往复荷载试验和ABAQUS有限元分析,得到试件的承载力,耗能能力,荷载-位移滞回曲线,分析了剪跨比对该新型材料剪力墙结构抗震性能的影响。试验结果表明:剪跨比是影响玻化微珠再生保温混凝土剪力墙抗震性能的重要因素,在剪跨比从2.2减小到1.2的过程中,再生保温混凝土剪力墙的承载能力提高,同时其延性耗能能力降低。Low-cycle repeated load test and ABAQUS finite element analysis were carried out for the recycled aggregate thermal insulation glazed hollow bead concrete shear wall,and the bearing capacity,ductility energy dissipation capacity and load-displacement hysteretic curve of the specimen were obtained.The experimental results show that the shear span ratio is an important factor affecting the seismic performance of the glass-reinforced concrete shear wall.In the process of the shear span ratio from 2.2 to 1.2,the carrying capacity of the recycled aggregate thermal insulation concrete shear wall is increased,and its ductility energy dissipation capacity is reduced.
