摘要: 由于钢箱梁的顶板、底板和腹板均较薄,在荷载作用下会由于截面变形产生畸变应力而发生局部屈曲和腹板 压皱等现象.为了提高钢箱梁的承载能力,设置横隔板是较为有效的措施.针对横隔板对钢箱梁畸变的影响进行分 析,并提出了横隔板的位置和间距对钢箱梁受力的影响.

Abstract: When applying the load onto the girder,its section may be distorted,and the girder may lead to partial flection,web plate crumple,and so on due to the reason that the top plate,bottom plate and web plate of the steel box girder are very thin.In that case,in order to improve the carrying capacity of the steel box girder,itg better to set enough stifening rib in the box girder.The distort efect of the diaphragm on the steel box girder was discussed.

Key words: steel box girder, diaphragln, distortion, warp stress, warp displacement
