摘要:
通过一榀单跨三层由方钢管混凝土柱-矩形钢管混凝土梁组成的矩形钢管混凝土框架的低周反复加载试验，研究了矩形钢管混凝土框架的破坏特征、承载能力、滞回曲线、骨架曲线和延性、强度与刚度退化、耗能等抗震性能．试验结果表明， 矩形钢管混凝土框架呈“强柱弱梁”破坏机制，试件破坏时三层梁端和一层柱脚全部出现塑性铰；试件的滞回曲线饱满，捏缩现象不明显，表现出良好的抗震性能；下降段较为缓慢，试件的整体强度、刚度退化现象不明显；试件的位移延性系数均大于3，破坏时各层层间位移角均大于1/50，满足罕遇地震作用下层间弹塑性变形要求；破坏时等效阻尼系数he 达到了0.441．分析结果表明，该类框架具有良好的工作性能和安全可靠性，可以应用于实际工程中．
Abstract:
A piece of 1 bay and three stories concrete-filled rectangular steel tubular (CFRST) frame was carried out in a low cyclic reversed loading test, which was composed of concrete-filled square steel tubular columns and rectangular beams. The failure characteristics, bearing capacity, hysteretic curve, skeleton curve and ductility, strength and stiffness degradation, energy dissipation were studied. The experimental results indicate that the CFRST frame showed the “strong column weak beam” failure mechanism, the beam ends and column feet all formed plastic hinges when the specimen damaged. The hysteretic curve of the CFRST frame is plump and the pinch phenomenon is not significant, which exhibits an excellent seismic behavior. The descending stage is gentl, and the overall strength and stiffness degradation is not obvious. The story displacement ductility coefficients are higher than 3 and the story displacement angle is higher than 1/50 when the specimen failed, which satisfy the story elastic-plastic deformation requirement under the rare earthquake. The equivalent viscous damping coefficient reaches 0.441 when the specimen failed. The analyses show that this kind of frame has good working performance and safety reliability, which can be applied to the practical engineering.
