Abstract:

Finite element analysis method was used in the research to check the mechanical characteristic of the 4 kinds of UHPCconcrete composite box girders(C60 concrete total crosssection, only UHPC roof, only UHPC bottoms and UHPC total crosssection). The accuracy of ANSYS analyzing and calculating for complex model should be verified before by using the test and the contrastive analysis of a rectangular UHPCconcrete composite beam. The ANSYS modeling method is determined by the result of comparative analysis in the same time. The stress distribution, bearing performance of 4 kinds of box girder were studied in the research. The structural behavior was summarized. The utilization of material properties, ultimate bearing capacity, strain distribution and economy should be considered, and some design advices were also given in the paper.

Key words:ultra high performance(UHPC); composite box girder; finite element analysis
