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。 Taking end-to-end moment ratio and eccentricity as the main parameters, six columns of CFST unequal-moment bent moment columns were tested. The results show that all the specimens are eventually damaged due to instability, and the ratio of end to end moment has a great influence on the failure modes of specimens. The larger the ratio of end moment to bending moment and the eccentricity, the smaller the stiffness and the ultimate load. At the same time, the relationship between the whole process of load-deformation of CFST columns with unequal ends was calculated by using the finite element method. The curves of failure mode and load-deformation are in good agreement with the experimental results.
