【摘要】 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。更多还原

【Abstract】 To analysis RHS frame seismic performance under different loads,this study investigates two kind of concrete filled RHS frame(with or without infill wall) including their bearing capacity,ductility,energy dissipation and collapse mechanism through on-site test methods.The results show that RHS frame with infill wall has plumper shuttle shape hysteretic curves,and excellent energy dissipation.The results have a useful reference value and are of significance to high-rise steel concrete structure.更多还原
