| Abstract: | This paper discusses the influences and their mechanism of compressive rigidity and flexural rigidity on the stress and deformation of concrete-filled steel tube(CFST) truss arch bridges.With reference to the practical testing data of an CFST truss arch bridge,the paper comparatively analyzes the effect of rigidity reduction in different specifications and in accordance with the differences of concrete quality of the different segments of the bridge,the paper also gives suggestion that the rigidity of the C... |
