一个边梁刚度的配置公式

An allocation formula for boundary beam rigidity

应用Fourier级数方法模拟了边梁的效应,分析了当边梁的扭转刚度不可忽略时边梁对板的影响,给出了一个边梁的弯曲刚度与扭转刚度的配置公式,从而有效地消除了板的挠度、弯矩、剪力等随边梁刚度的增大而增大的不合理现象,对忽略边梁的抗扭能力所导致的误差也做了定量分析.

The responses of boundary beams are simulated with Fourier method, and the effect of the boundary beams to the plate is analyzed especially in the case. Where the torsion rigidity of the beams cannot be ignored, the relationship between the bending and torsion rigidity of the beams is presented. The irrational phenomena that the displacements, moments and shearing forces of the plates increase as the rigidity of the beam increases are avoided. The errors due to disregarding the torsion rigidity of the beams are analyzed as well. 
