加劲肋是在支座或有集中荷载处，为保证构件局部稳定并传递集中力所设置的条状加强件，可以提高梁的稳定性和抗扭性能。加劲肋适宜在腹板两侧成对配置，也可单侧配置。
The thickness variation of bottom plate,web plate and web stiffener has a definite effect on local stability of steel-box girder,because the area ratio of them is limited in the girder.
底板、腹板和腹板加劲肋对钢箱梁的局部稳定有一定的影响,但考虑到本桥中腹板和底板所在区域有限,所以板厚变化对钢箱梁的局部稳定性提高作用有限。
