摘要

根据/4环、半圆环和全圆环节点形式的试验研究和有限元分析初步探索了钢管插板节点受弯的力学性能，并提出了这种节点的承载力确定方法及简便计算公式，在与日本《输电线路钢管塔制作基准》对比分析中，得出了承载力和不同参数的关系曲线。结果表明：极限承载力不仅与主管壁厚t、管径D、节点板长度B、现时状态下屈服区域内中截面顶部挠度δ有关，更重要的是还和现时状态下的加劲肋有密切相关。承载力计算公式对工程设计有重要的应用价值。

Abstract

This paper explored bending performance of tubegusset joint primarily according to experiment and finite element model. The method which is used to determine ultimate strength of the joint was proposed on the base of three joint types including /4 circle ribbed

half circle ribbed and circle ribbed stiffeners. Compared with the Japanese electricity transmitting steel tubular tower manufacture norm

a conclusion has been drawn that the ultimate strength has relationship with several different parameters. The result shows that the ultimate strength of the joint is related not only to the wall thickness t

diameter D

length of gusset plate B and the yield deflection δ at the top of the relevant section under the current status of the region

but also to the ribbed plate. The formula about ultimate strength has important application value for engineering design.
