Influence of Prestress Loss on Mechanical Performance of Fabricated Girder Bridge
There are many prestressed concrete prefabricated girder bridges with small and medium span and the damage is serious. This paper mainly studies the influence of prestress loss on the mechanical performance of prefabricated girder bridges. Through the establishment of ANSYS finite element model, from different conditions of prestress loss research, the stress and strain data were obtained and the curves were drawn. The final analysis resulted in the following conclusions: The loss of prestress will reduce the ultimate bearing capacity of the bridge. The effect on the middle deflection of the side span is greater than that on the middle deflection of the secondary side span and the middle span. Therefore, the prestress loss and the effective prestress should be strictly considered in the design and construction process.
