摘要
通过对门式刚架楔形梁稳定系数和临界弯矩计算公式的分析,找出其主要的影响因素并进行了详细探讨。通对对梁面外稳定性的分析,为实际工程的屋面楔形梁设计提供了理论依据,并通过工程算例进行了验证分析。
Through the analysis of the stability coefficient and the critical moment formula of the portal frame tapered beam, the main influencing factors are found out and discussed. Based on the analysis of out-plane stability of beam, it provides a theoretical basis for the design of the tapered beam in practical engineering, and an engineering example is given to verify the analysis.
