Study on the Mechanical Characteristics of Wet Joint Damage of Concrete Box Girder Bridge
In order to study the influence of different wet joint connection modes on the mechanical characteristics of concrete box girder,the article relies on a concrete box girder bridge of an expressway.With the help of Midas Civil finite element software,the grillage method is used to model and simulate the concrete box girder bridge.The stress of the wet joint under partial load and medium load is analyzed,and the transverse distribution coefficient under different wet joint damage degrees is analyzed.The results show that the connection mode of wet joint has a direct influence on the transverse connection of box girder.The transverse increase coefficient increases with the increase of the damage degree of wet joints,which provides reference for the design and maintenance of wet joints of concrete box girder bridges.
