Abstract

Abstract

In order to study the effect of tube rigidity on the mechanical character of truss CFST(concrete filled steel tubular)arch bridge, a true arch bridge was taken as sample, and the parameter analysis for the rigidity was carried out by using finite element model.Based on the investigation of section composition for arch rib, a suggestion was presented to calculate tube rigidity, in which the rigidity reduced factor of concrete was adopted as 1.0 or 0.4 for different calculation demands.Analysis result indicates that for internal force, the rate of calculation value to reality value is between 1.2 and 1.5, for deformation the rate is between 1.5 and 1.9.So, the suggestion can secure some safety reserve for the design of truss CFST arch bridge.
