| 摘 要： | 为了研究内加劲环间距对X型圆管相贯节点性能的影响,对加劲环设置情况各不相同的4个X型相贯节点试件进行试验研究与有限元分析.介绍了试验方案、有限元模型,并对试验和有限元计算结果进行对比分析.结果表明:内加劲环的设置对X型节点受力性能有一定的提高;当位于主支管相贯范围内,内加劲环对节点的强度、刚度等受力性能的提高幅度较大;...

| Abstract: | In order to research the influence of the spacing of internal ring-stiffener on behavior of X-joints,four X-joints which had different settings of stiffener were tested and analysed with finite element method.The test procedure and the finite element model were presented and the results of test and finite element calculation were compared and analysed.The results show that setting internal ring-stiffener can improve the mechanical properties of joints to some extent.When the stiffeners are in the range of j... |
