摘要
利用非线性分析的有限元方法对K型和双K型圆管相贯节点进行了数值计算,揭示了节点极限承载力随各几何参数的变化规律及主管作用荷载对节点极限承载力的影响,分别绘制出各影响参数的载荷-位移曲线,并将分析结果和钢结构标准GB50017-2003进行了比较,所得结论供工程设计参考应用。
In the paper, nonlinear finite element analysis on the tubular K, KK-joints (Circular Braces) is carried out. The rules are summarized from the relation between the ultimate strength and parameters. The results from the models are compared with the solution gotten from the code for steel structure(GB50017-2003) , some useful conclusions are suggested for construction projects.
