内置CFRP圆管的方钢管混凝土梁柱节点力学性能研究

Study on Mechanical Properties of Concrete-filled Square Steel Tubular Columns and Columns with CFRP Round Tubes

通过对一种穿心式的内置CFRP圆管的方钢管混凝土节点进行单调静力加载试验,并利用ANSYS软件对试件进行建模计算分析,并将试验与有限元结果进行对比,二者吻合程度良好.研究结果表明:这种组合结构的穿心型节点承载力较高、延性较好.

The monotonic static loading test is carried out on a square steel tube concrete joint with a built in CFRP tube. The ANSYS software is used to analyze the modeling s, and the software. Then,the test is compared with the finite element result. ,which shows the two are in good agree ment. The results show that the core type joints of this combined structure have higher bearing capacity and better ductility.
