摘　　要：采用拟静力试验方法,探究轻钢骨架秸秆混凝土装配式墙体的抗震性能。通过对裂缝、滞回曲线、骨架曲线、延性、刚度退化和钢材应变等试验结果分析,结果表明:该新型结构墙体在反复荷载作用下,既能发挥秸秆混凝土材料优良的延性性能,又能充分利用内部钢骨架的销键和约束作用;在1/100的侧向位移角条件下墙体竖向承载力不变,侧向承载力仅达到最大值的70%。The pseudo-static test method is used to study the seismic performance of the light steel skeleton reinforced strawconcrete fabricated structure wall.Through the cracks,hysteretic curves,skeleton curves,ductility,stiffness degradation andsteel strain test results analysis,the results of fracture,hysteresis curve,skeleton curve,ductility,stiffness degradation andsteel strain were analyzed,it showed that the new structure wall under repeated load can play an excellent ductilityperformance of straw concrete material,also can make full use of the internal steel pin key and constraint function;thevertical bearing capacity of the wall is unchanged at1/100of the lateral displacement angle,and the lateral bearing capacityis only up to70%of the maximum.
