为了钢管混凝土框架结构在不同荷载作用下抗震性能的分析。通过现场试验的方法,对有无填充墙的两种钢管混凝土框架结构进行了在承载能力、延性、耗能能力以及破坏机制的分析研究。研究结果表明:两种框架结构在进行水平低周反复加载试验,带填充墙矩形钢管混凝土框架结构较无填充墙的框架结构其滞回曲线更加饱满,耗能能力强等抗震性能。该成果对高层钢管混凝土结构具有一定的参考价值和指导意义。
Seismic behavior analysis of concrete filled steel tubular frame under different loads. Through the field test, two types of CFST frame structures with or without infill walls were analyzed in terms of bearing capacity, ductility, energy dissipation capacity and failure mechanism. The results show that the two kinds of frame structures are subjected to the horizontal low cycle repeated loading test. The frame structure of the rectangular CFST with infilled walls is more full of the hysteresis curve and has the better energy dissipation capability than the frame without the infilled wall. The results of the high-rise concrete-filled steel structure has a certain reference value and guiding significance.
