| 摘 要： | 平面K型节点是钢管结构节点主要形式之一。对平面K型圆钢管搭接节点在静力荷载和冲击荷载作用下的弹塑性响应和极限承载力进行了非线性有限元分析。首次得到相贯节点的动力极限承载力,发现节点的动力极限承载力一般小于静力极限承载力。K型圆钢管搭接节点在静、动荷载作用下弹塑性力学特性有较大的区别,节点动力破坏主要发生在节点相贯处,规范计算公式给出的节点静力极限承载力是偏于保守的,所得计算结果和结论对实际工程有一定的应用价值。

| Abstract: | The planer tubular K-joint is one of the main joints in the steel tubular structures.The elastic-plastic response and the static and dynamic ultimate bearing capacity of the planer steel tubular K-joints are investigated by the nonlinear finite element method.The dynamic ultimate bearing capacity of the over-lapped K-joint is firstly obtained.From these computational results,it is found that some significant differences exist between the static and dynamic response characteristics.In general,the destroy of ... |
