Abstract:

Prefabricated small box girder bridges have been widely used in urban viaducts and highway bridges at home and abroad. Concrete deck paving and guardrails are well bonded to the main girder, which contributes to the rigidity of the main girder structure. Ignoring the influence of the auxiliary structure of the bridge deck will cause a certain deviation between the structure and the actual state. This paper takes the prefabricated box girder bridge as an example, using the finite element method to analyze the variation of the lateral distribution coefficient of the bridge deck and guardrail and the degree of influence on the main girder force. The calculation results show that the bridge deck pavement has little effect on the lateral distribution coefficient of the main girder, the increase in the rigidity of the main girder by the guardrail cannot be ignored, and the difference in the bearing capacity and stress of the side main girder is significant.
