摘要
目前输电铁塔中的圆截面钢管应用较多,首先介绍了钢管节点的加强措施,表明内加劲环是一种很好的加强措施。然后采用有限元ANSYS软件着重对空间KK型圆钢管相贯节点加劲前和加劲后的极限承载力进行研究,通过分析比较,得出结论,为实际工程提供参考。
At present, the round steel pipe section is used more often in transmission tower. This paper introduces the strengthening measures for steel pipe node, which show that ring-stiffener is a kind of good strengthening measure, and focuses on the research of ultimate bearing capacity of space type KK-intersecting nodes by ANSYS finite element analysis software, trying to find the differences between the node with ring-stiffener and without ring-stiffener. Finally, the paper obtains a conclusion based on the analysis and comparison that provides a reference for practical engineering.
