摘要 文中通过钢板等效替换为箍筋截面积的方法,以增加箍筋的方式来进行抗剪加固计算。以某高速公路13m钢筋混凝土空心板桥为研究对象,通过Midas/civil 2020有限元软件进行建模分析,讨论粘贴不同厚度钢板对桥梁抗剪承载力的影响。结果表明粘贴钢板提供的抗剪承载力与钢板厚度几乎呈线性增加,此时桥梁的破坏极限荷载明显提高,其破坏是由抗弯承载力不足引起。 The purpose of this paper is to replace the cross-sectional area of stirrups with steel plates equivalently and increase the stirrups to calculate the shear reinforcement.Taking 13m reinforced concrete hollow slab bridge of an expressway as the research object.Simulation and analysis are carried out by Midas/civil 2020 finite element software.The influences of pasting steel plates of different thicknesses on the bridge’s shear capacity is discussed.The results show that the shear capacity provided by the bonded steel plate increases almost linearly with the thickness of the steel plate.The damage limit load of the bridge is significantly increased,and the damage is caused by insufficient flexural capacity.
