Load Lateral Distribution of Rigid Frame Arch Bridge Strengthened with Arch and Stayed Cable System

Aimed at outline and measures for strengthening the traditional reinforced concrete elastic supported continuous beamstribution of arch and stayed cable system was put forward. , assuming that load effect exists in bridge spatial structure composed of arch rib stiffness at section under the load stiffness , an elastic supported continuous transverse beamhed for calculating load lateral allocation at arch. Thus, the spatial calculating comparisons between spatial test show that the reinforced concrete rigid frame archned with arch and stayed cable system can effectively enhance the ultimatet is partial to safety.
