碳纤维板加固桥梁的承载性能
Bearing Capacity of Carbon Fiber Plate Reinforced Bridge
摘要
Abstract
In order to explore the influence of carbon fiber plate on the bearing capacity of the bridge,the model of Dongtiaoxi Bridge was established by Midas Civil software,and the sinking deformation,shear bearing capacity and torsional bearing capacity of each bridge section were calculated and analyzed,and the shear failure area was delineated.With addition of carbon fiber plate in the vulnerable area,the nu-merical analysis of the original bridge and the bridge reinforced by carbon fiber plate is carried out.It is found that the bridge body strengthened with the carbon fiber plate has a significant improvement in bearing performance,in which the settlement amplitude is reduced by 27％,and the shear torsion resist-ance is increased by 10％.关键词
