| 摘 要： | 通过对8个薄壁钢管混凝土柱与组合梁节点的试验研究,得出了各类节点受力性能的一般规律.试验证明,各节点均具有较高的承载力和较好的延性性能.采用ANSYS有限元程序中的Solid 65单元和Shell 181单元分别来模拟组合梁、柱中的混凝土和薄壁钢板对节点进行有限元分析,理论计算结果与试验基本吻合.

| Abstract: | Experiment on joints of concrete filled thin-walled steel tube and composite beam is carried out in 8 specimens,and mechanics performance of all type joints is concluded in general.Test results indicate that each joint has higher bearing capacity and better ductility performance.The Solid65 and Shell181 Elements of ANSYS finite element program are adopted to simulate concrete and thin-walled steel sheet of composite beams and columns.Calculation results in theories is proved conformity with the test in primary. |
