摘要

钢管混凝土结构在我国得到了广泛的应用,国内外学者对钢管混凝土结构进行了很多研究。通过电液伺服系统进行了方钢管混凝土柱常轴压低周反复荷载作用试验,分析其在低周反复水平荷载作用下的延性性能与耗能能力,给出位移随反复荷载变化的滞回曲线。试验结果显示,整个加载过程所得到的2试件荷载—位移曲线呈"梭形",表明方钢管混凝土结构具有良好的延性和耗能能力,抗震能力强。
Concrete-filled steel tube(CFST) structures has been extensively applied in engineering in China and the scholars at home and abroad have carried out a large number of researches on concrete-filled steel tube structures.The properties of concrete-filled square steel tube(including ductility behavior and energy dissipation) are studied under normal axial pressure and low frequency loading by electro-hydraulic servo system and the hysteretic curves of displacement changing with periodic loads are obtained.The test results show that in the loading process,the load-displacement curves of the two experimental members have a shuttle shape,which means that concrete filled square steel tube-pile has good ductility,energy dissipation capacity and anti-seismic property.
