摘要
基于钢筋混凝土异形柱框架节点的试验,运用大型通用有限元软件ANSYS对T形柱节点进行了非线性有限元分析,并与试验结果进行了对比。简化T形柱为矩形柱,对比简化前后两节点的骨架曲线。并改变T形柱翼缘肢长,分析了翼缘对节点受剪承载力的影响。研究表明,非线性有限元计算结果与试验结果吻合较好,可以对节点承载力进行分析;使用矩形柱节点公式对T形柱节点受剪承载力计算误差较小,且T形柱节点的翼缘对节点的抗剪承载力贡献较小,主要由腹板承担。
T-shpaed joints under single loads are analyzed by the FEM program ANSYS. The comparison between experimentation and computation shows that the model is available. The T-shaped column was simplified as rectangular column,and their skeleton curves are compared with each other. Change the length of the flange,and analysis the difference on shear bearing capacity. The results show that it is possible to use the shear bearing capacity formula on T-shaped column joint,the error is small. In the T-shaped column joint,the load is borned by web.
