摘　　要：通过3块保温复合铁尾矿混凝土剪力墙的设计和互相对比试验,得出其荷载-应变曲线、荷载-位移滞回曲线和荷载-位移骨架曲线以及延性系数等结果,判断该新型保温复合剪力墙体系的抗震性能与可行性。结果表明:该铁尾矿混凝土制成的剪力墙比普通混凝土剪力墙的脆性大,抗震性能较弱,而剪力墙的钢筋布置和模板设计均满足条件。同时,针对此复合剪力墙体系的设计与试验,以期为铁尾矿混凝土和该新型复合剪力墙体系的应用和推广提供一定的参考数据和价值。Through the design and comparative test of three thermal insulation composite iron tailings concrete shear walls,the load-strain curve,load-displacement hysteretic curve,load-displacement skeleton curve and ductility coefficient were obtained,and the seismic performance and feasibility of the new thermal insulation composite shear wall system were judged.The results show that the shear wall made of iron tailings concrete is more brittle than ordinary concrete shear wall,and its seismic performance is weaker,while the reinforcement arrangement and formwork design of the shear wall meet the conditions.At the same time,aiming at the design and test of this composite shear wall system,in order to provide some reference data and value for the application and popularization of iron tailings concrete and this new composite shear wall system.
