本文对带隔板的連續箱形梁应用有限条法——柔度法进行計算机分析。横隔板取不同的計算图式——刚性隔板、平面应力板及平面支架,并編制了相应的計算机程序。文中通过实例分析以及对比两个模型梁的测試結果,探討了横隔板不同計算图式对箱形結构应力的影响,箱与隔板的抑制点的选择。諧函数的收敛,隔板內力分析等问题。
In this paper, the finite element method - the flexibility method is used in the computer analysis of the continuous box girder with diaphragm. Diaphragm to take different calculation drawings - rigid partitions, plane stress plate and plane bracket, and the preparation of the corresponding computer program. In this paper, through the example analysis and comparison of the test results of two model beams, the influence of different calculation schemes of diaphragm on the stress of box-shaped structure and the selection of suppression points of tank and diaphragm are discussed. Harmonic function convergence, diaphragm internal force analysis and other issues.
