钢管混凝土斜折柱抗震性能试验研究
|
摘要
为解决实际工程中遇到的钢管混凝土斜折柱抗震性能的问题,进行了3个1/3缩尺的钢管混凝土斜折柱低周反复荷载试验。在试验基础上,研究了各钢管混凝土柱的承载力、刚度、延性、滞回特性及破坏特征,建立了钢管混凝土斜折柱承载力简化计算方法。研究表明:钢管混凝土斜折柱,经合理设计可以满足抗震要求。
In order to ascertain the seismic performance of the concrete filled steel tube columns with gambrel appeared in the practical engineering,three 1/3 scaled concrete filled steel tube columns with gambrel were carried out under cyclic loading test.Based upon the test,the bearing capacity,stiffness,ductility,hysteretic curves and failure characters between the concrete filled tube columns are compared.And a simplified calculation method for bearing capacity of the concrete filled steel tube column with gambrel is established.The results show that the concrete filled steel tube columns with gambrel meet the seismic requirements through reasonable design.
