摘要
Abstract
With its unique advantages, composite box-girder bridges with corrugated steel webs are gradually adopted by domestic and foreign bridge designers, however, the optimization analysis of this composite girder is rare. In this paper, by using the finite element analysis software ANSYS, the finite element model of optimization analysis of composite box-girder with corrugated steel webs was established. First, the multivariable optimization analysis on the cross-section parameters of corrugated webs was implemented, and then, based on this optimization analysis results, the optimization analysis on the cross section of a simply supported girder with a span of 30 m was also implemented. As a result, the optimum values of the corrugated steel web dimensions and the section parameters of box-girder were obtained.关键词
