Abstract

Abstract

With regard to a two-span continuous curved bridge with steel box girder, finite element analysis modelwas established by using shell elements, and the stress of steel box girder was computed under different loadingconditions. The reason that results in unevenness of stress distribution at both top and bottom slab of curved steel boxgirder was studied through analysis, and the pattern of stress unevenness was also obtained in this paper. In the end, the unevenness coefficient of stress distribution at both support and mid-span of curved box-girder bridge was definedand a reasonable value was proposed, which may provide a reference for the design of similar bridge structures.
