摘要
采用有限元程序ANSYS对钢管混凝土柱与桁架穿心螺栓端板式连接节点进行单调加载和循环加载作用下的受力性能分析。有限元分析结果与试验基本吻合。在此基础上对节点进行了参数分析,研究了轴压比、钢管柱壁厚度、核心混凝土强度、螺栓级别及直径对节点受力性能影响。结果表明,轴压比和钢管柱壁厚度对节点受力性能影响较大。
The ANSYS finite element package is used to simulate the nonlinear behavior of the concrete filled square steel tubular column-to-truss through bolts-end plate connections under the monotone and cyclic loading.The load-deflection curves by the finite element analysis show good agreement with the experiments.The parametric analysis were consequently conducted to investigate the influence of the compression ratio,the steel tube wall thickness,the concrete strength in the steel tube,the level and diameter of the bolt on the property of the connections.The results show that the compression ratio and the steel tube wall thickness greatly influence the connections.
