梁格法分析箱梁的弯曲效应研究
The grillage method analysis of box girder bending effect research
摘要
Abstract
Grillage analysis method to calculate the calculation precision of box girder bending effect, USES the grillage method analyzed the effect of box girder bending by the methods of experiment and numerical simulation, obtained the grillage theory to analyze the calculation precision of box girder bending effect. Under concentrated load, single box 3 rooms box girder peak stress calculation results with the experimental solution of the maximum rate of 14.7%, numerical solution and the plate and shell's 4.2%. Under the action of uniformly distributed load, different supporting system solution of the beam of the peak stress and the ANSYS maximum rate of 7.94%. Article can be thought of beam theory based on the analysis of single box chamber when the stress of the box girder has good analytical precision.关键词
