Considering the influence of that crossbars of arch rib of CFST arch bridge on vertical bending rigidity and torsional rigidity of the whole bridge system,the space finite element calculating model for a CFST arch bridge with span of 400 m was set up by using common software ANSYS.

On the consolidation programs of side arch rib of Xinguang Bridge;

Linear control of prefabrication and hoisting of arch rib in Taipinghu bridge;

Technology research on arch rib construction of bridge arch of steel tube concrete in the middle part;

Based on the constitutive relation of combinatorial material of concrete filled steel tube(CFST),the calculation analyzes linear and nonlinear reactions of rib arch under static loads.

Quyi Bridege of Fu an City is a concrete-filled steel tubular (single tube) rib arch bridge.

In this paper, two model experiments of the concrete-filled steel tubular (CFST) rib arch under in-plane loads are reported.

Based on experimental study on two 28-year-old existing reinforced concrete arch ribs, the load-displacement and load-strain relationships, the residual load carrying capacity and the failure pattern are explored.

Horizontal push will arise Pier displacement of the through arch bridge of concrete-filled steel tubes under the condition of erection of arch ribs, concreting process, transverse beam pouring and installation.

In the concrete filled steel tubular arched bridge construction process,in order to guarantee that structure satisfies linear and intensity request after concrete filled steel tubular arched bridge is completed,according to control survey principle and the technical request,the method of controlling stress and distortion is used to control the line form of the arch ribs.
