摘要

摘要: 以端弯矩比和偏心距为主要变化参数,对6根圆钢管混凝土不等端弯矩偏压柱进行试验研究。结果表明:所有试件都最终由于失稳而破坏,端弯矩比对构件破坏形态有很大影响;试件的端弯矩比和偏心距越大,其刚度和极限荷载越小。同时采用有限元方法对圆钢管混凝土不等端弯矩偏压柱的荷载-变形全过程关系进行计算,得到的破坏形态和荷载-变形关系曲线与试验结果符合较好。

Abstract: A total of 6 concrete-filled circular steel tubular columns were tested under eccentric load of unequal end-moment.The primary parameters in the tests were end-moment ratio and max eccentricity.The results show that all the specimens were destroyed due to the instability ultimately,end-moment ratio has important effect on the failure modes of the specimens;the greater the end-moment ratio and the eccentricity ratio,the smaller the rigidity and the bearing capacity.On this basis,the behavior of concrete-filled circular steel tubular columns under eccentric loading of unequal end-moments is analyzed by finite element method.The calculated results agree well with the experimental results.
