横隔板对波形钢腹板曲线箱梁应力影响研究
The Influence of Diaphragm Plate in the Corrugated Steel Web Curve Box-Girder Bridges

利用有限元软件对某曲线箱梁桥进行分析计算,对比分析在跨间设置不同数目和不同位置横隔板的情况下,箱梁顶板内外缘正应力的变化.分析结果表明:横隔板设置的位置和数量对曲线波形钢腹板箱梁桥的应力有显著影响,并为波形钢腹板曲线箱梁桥的设计提供参考.
By using FEA program,one curve box girder bridge is calculated and analyzed,and the normal stress change of box girder roof inside and outside edge is contrasted in setting up different number and different position diaphragm plate,the results show that the position and number of the diaphragm plate in curve corrugated steel web box girder bridge has a significant influence on the stress.The best diaphragm plate number and position for corrugated steel web curve box girder bridge is designed to provide reference
