摘　　要：法兰连接是钢塔圆管构件之间的一种主要连接方式,其中,法兰板厚的设计是法兰设计的主要部分之一。国内不同规程与标准之间的法兰板最大弯矩系数不同,为设计者带来了疑问和设计困难。本文通过实例分析以及有限元建模论证,对比在不同规程条件下设计法兰板厚的情况,进而针对法兰板厚的设计过程做出了相应结论和建议。Flange connection is main method of the components connection in the tube steel tower structure, and determining the flange thickness is one of the main parts in flange design. Different regulations and standards for flange thickness design contain different moment coefficients, and this brings engineers into difficulties in designing. Through case analysis on moment coefftcients and establishment of finite element models, groups of flange thickness from different standards are compared. Moreover, conclusions and recommendations are made for the flange thickness design process.
