Research of Elastic Camber for Prefabricated PC Girder
In the process of prefabricating some genenal box girder,T girder,I girder,cored slab,a tension of prestress will give rise to the camber which is the important evaluation criterion of bridge engineering quality.This paper take XiHuXiuZi bridge and FuXingPao bridge as background to research elastic camber of prefabricated PC girder.Then the model of prefabricated PC girder is established through finite element analysis software Ansys.The model data is compared with the collected data after finishing the model.The factor which can impact elastic camber is researched deeply.Lastly,the relations between the elastic camber of prefabricated PC girder and each influential factors is determined through changing model parameters.
