摘　　要：将足尺寸钢纤维泡沫混凝土复合墙板与半刚性连接节点钢框架组成的钢框架一墙板结构与空框架结构进行对比,对其分别进行相同试验条件下的水平拟静力荷载试验.通过分析试验现象和数据得到两组框架的滞回曲线、骨架曲线。结果表明:足尺寸钢纤维泡沫混凝土复合墙板增强了结构的整体受力性能,钢框架一墙板结构比空框架结构的耗能能力强、刚度增大、刚度退化缓慢、延性系数不变、极限承载力提高45%、自振周期降低20%以上,同时半刚性连接的梁柱节点可以增强结构的整体抗震性能。The steel frame-wallboard structure composed of the full-size steel fiber foam concrete composite wallboard and the semi-rigid joint steel frame was compared with the empty frame structure,and the horizontal quasi-static load test under the same test conditions was carriSd out separately.The hysteresis curves and Skeleton curves of the two sets of frames were obtained by analyzing the experimental phenomena and data.The results show that the steel fiber foam concrete composite wallboard of the full size enhances the overall mechanical performance of the structure.The steel frame-wallboard structure has stronger energy dissipation capacity,increased stiffness,slower stiffness degradation and constant ductility coefficient, compared with the empty frame structure.The ultimate hearing capacity is increased by 45% and the natural vibration period is reduced by more than 20%.At the same time,the semi-rigid connection of beam-column joints can enhance the overall seismic performance of the structure.
