本文研究了塔桅结构中钢管有加劲肋法兰盘连接的抗拉受力性能，并用有限元方法对几个节点进行了计算分析，揭示了法兰盘在轴向拉力作用下的受力特点，将计算结果与《高耸结构设计规范》（ＧＢＪ１３５ － ９０） 的计算结果进行了对比，为修编《高耸结构设计规范》中法兰节点连接章节提供了一定的参考依据。
In this paper, the tensile and mechanical properties of steel stiffened rib flanges in steel tower structure are studied, and several nodes are calculated and analyzed by finite element method to reveal the force characteristics of the flange under axial tension. Comparing the calculation results with the calculation results of the “High-rise Structural Design Code” (GBJ135-90), it provides a certain reference for revising the chapter on flange connection in the “High-rise Structure Design Code”.
