空腹箱形钢骨混凝土构件的抗扭性能研究

RESEARCH ON BEHAVIOUR OF BOX-HOLLOW SRC MEMBERS SUBJECTED TO TORSION

基于合理的材料本构关系模型,利用ABAQUS软件对空腹箱形钢骨混凝土构件在扭转荷载作用下的荷载-变形关系曲线进行计算,计算曲线与试验曲线基本吻合。在此基础上,对空腹箱形钢骨混凝土纯扭构件的工作性能进行分析,结果表明:这类构件具有较好的延性性能。

Based on rational constitutive model of steel and core concrete, the present study is an attempt to investigate the behaviours of box-hollow SRC members subjected to torsion. ABAQUS software is used in this paper for the finite element analysis （FEA）. A comparison of results calculated using this model shows good agreement with test results generally. Based on numerical results, the behaviour of box-hollow SRC members subjected to torsion was analysed and found that this type of member has good ductility.
