摘　　要：对保温结构新体系——玻化微珠保温墙模复合剪力墙体系中的高剪跨比剪力墙进行低周往复荷载试验研究。通过对比试验的方法,研究了保温墙模复合剪力墙与普通实体剪力墙在承载力、刚度、延性等方面的性能。试验结果表明:复合剪力墙的承载力较普通剪力墙的仅降低约7%,而刚度却明显减小,既使结构有较高的安全储备,又使延性得到明显改善,该体系在结构抗震方面能发挥较大潜力;墙模与内部混凝土的粘结能力强,共同工作性能良好。研究成果可以作为保温墙模复合剪力墙工作性能评价与工程设计的理论依据。A low-cyclic load test was carried out on large shear span ratio composite shear wall structures with heat preservation formwork by glazed hollow bead （GHB） , which is a kind of new insulation structure system. The test was conducted to compare the performance of composite shear wall and ordinary solid concrete shear wall in terms of bearing capacity, stiffness and ductility. Results show that compared with ordinary solid concrete shear wall, the stiffness of composite shear wall reduces significantly while the bearing capacity reduces about 7%. Composite shear wall is characterized by higher safety reserve and significantly better ductility, which indicates this composite shear wall has greater performance in seismic design. The test results also demonstrate that the formwork of composite shear wall works together with internal concrete as a whole. Study results can be applied in design and performance evaluation of composite shear wall structure with heat preservation formwork.
