摘要
利用有限元分析软件ABAQUS对圆钢管混凝土曲杆受压时的荷载-变形全过程曲线进行模拟,模拟结果与试验结果吻合良好。在此基础上,通过计算分析,对钢管混凝土曲杆与曲线形空钢管破坏形态的差别进行比较,最后对有关钢管混凝土曲杆的力学性能进行分析。
It is attempted to study the compressive behavior of curved concrete-filled circular steel tubular struts. Nonlinear finite element analysis software --ABAQUS is used for the analysis of load versus deformation relations of the strut members. The calculated results show generally good agreement with the test results. The failure mode of curved concretefilled steel tubular struts is compared with that of empty curved steel tubes. The behavior of the curved composite members are analyzed and discussed.
