盖梁粘钢法加固的效果分析评价

Analysis and evaluation of the reinforcement effect of Steel Plate Adhering to the Queen-Post Girder

针对某座桥梁下部结构盖梁采用粘钢法进行加固,对其加固效果采用有限元模型进行仿真分析计算,并通过现场荷载试验进行验证。理论分析与荷载试验结果的一致性表明采用有限元仿真分析方法能够对桥梁加固效果进行准确的评价。

In this paper, the reinforcement method with steel plate adhering to a real queen-post girder in bridge was analyzed by using the space entity simulation model, and the effect was validated by load test on site. The result uniformity of theory and test illustrates the simulation analysis method with finite element can be used to evaluate the reinforcement effect of bridge well and truly.
