多腔扁钢管混凝土斜折柱抗震性能试验研究
|
摘要
大连国际会议中心结构幕墙柱中,采用了一种扁钢管混凝土斜折柱。文中结合该工程设计,进行了2个1/3缩尺的扁钢管混凝土斜折柱试件的低周反复荷载试验,1个试件为普通扁钢管混凝土斜折柱1,个试件为多腔扁钢管混凝土斜折柱。比较分析了两个试件的承载力、刚度、延性、滞回特性及破坏特征。研究表明:多腔扁钢管混凝土斜折柱与普通扁钢管混凝土斜折柱相比,具有抗震耗能能力强、延性好的特点,可用于工程设计。
The flat concrete filled steel tube column with gambrel has been used in the curtain wall column at the project of Dalian International Conference Center.Two 1/3 scaled specimens were designed according to the actual project and tested under the cyclic loading.One of the specimens was the ordinary flat concrete filled steel tube column with gambrel and the other was the flat multi-cavity concrete filled steel tube column with gambrel.Bearing capacity,stiffness,ductility and failure characters of the two specimens were analyzed and compared.The results show that: compared with the flat ordinary concrete filled steel tube column with gambrel,the flat multi-cavity concrete filled steel tube column with gambrel has higher seismic energy dissipation capacity and better ductility,and it can be applied in the practical engineering project.
