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 one of the main connections between the steel pipe and tube components. Among them, the flange thickness design is one of the main parts of flange design. Different rules and standards of the flange between the maximum bending moment coefficient, the designer has brought questions and design difficulties. Through the example analysis and finite element modeling demonstration, this paper compares the design of flange plate thickness under different procedures and conditions, and then makes the corresponding conclusions and recommendations for the design process of flange plate thickness.
