| Abstract: | Taking a concrete-filled steel tubular arch bridge as the basic analysis object,this paper establishes a three-dimensional simulation numerical model for and analyzes the ultimate bearing capacity of concrete-filled steel tubular arch bridges under coupling action of various factors,and the paper also discusses in details the effect of the initial geometric imperfection,live load proportion,load distribution forms and steel content ratio on the ultimate bearing capacity of the arch bridges and eventually generalizes some helpful conclusions. |
