摘要
粘贴钢横梁加固方法目前是加固铰缝受损的空心板梁常用的加固方法,此方法极大地改善了铰缝受损的空心板梁的"单板受力"病害,通过提高横向分布系数减小作用力来使桥梁承载力满足要求。论文对有竖向预应力筋的钢横梁加固法有限元建模方法进行研究,为相关工程提供参考。
The strengthening method of bonded steel beam is commonly used to strengthen hollow slab beam with damaged hinged joints.This method greatly improves the "single plate force" disease of damaged hollow slab beam with hinged joint. The bearing capacity of the bridge is satisfied by increasing the transverse distribution coefficient and reducing the force. This paper researches the finite element modeling method for steel beam reinforcement method with vertical prestressed reinforcement, to provide reference to related engineering.
