【摘要】 基于ABAQUS有限元分析软件,建立了圆形钢管混凝土高桥墩的非线性有限元计算模型。分别对不同径厚比、轴压比、混凝土强度的计算模型进行了低周反复荷载试验下全过程的非线性分析,得出了相应的滞回曲线、骨架曲线。并对以上计算结果进行了分析,得到了一些有工程建设意义的结论。更多还原

【Abstract】 Based on the ABAQUS software,the non-linear finite element calculation model for high bridge pier of concrete-filled round steel pipe was established.The non-linear analysis of the whole process under low-cycle repetitive load tests was made for calculation models with different diameter-thickness ratio,axial-load ratio,and concrete strength,and the corresponding hysteresis curve and the skeleton curves were derived.The abovementioned results were analyzed,and some profitable conclusions for engineering construction were obtained.更多还原
