The Cable Anchorage Zones Stress Analysis Of Cable-stayed Bridge With Single Sower Double Planes

This article describes the cable stayed bridge girder anchorage zone design principlesand several common forms of Cable-Girder Anchorage and Anchorage Zones stressanalysis of the status quo. For cable-stayed bridge anchorage within the section,especially cable junction beam, because the huge anchor cable tension andconcentration of local effects, making the region more complex beam force, coupledwith concrete material nonlinearity, holes weaken and prestressed construction processerror and other factors, in the design and construction, if not its local analysis, it isdifficult to understand the structure of the actual working conditions and stressdistribution. The traditional cable-stayed bridge Cable-Girder Anchorage in the longterm dynamic loads and static loads, prone to fatigue or intensity of destruction.Thecurrently common types of Cable-Girder Anchorage forms stress concentration.Therefore, this paper Libo Guan Tang Bridge as engineering background, since theinclination of a small cable-stayed bridge, away from the big cable, cable force, makingAnchorage Zones stress concentration phenomenon is more obvious. The bridgereinforcement anchorage zone more when pouring concrete in construction, prone tofilling is not dense concrete situation. This article first bridge through midas model todetermine the state of different load combinations into the case, the relevant unit ofelement forces and boundary conditions, according to the results using the finiteelement analysis software ansys right Anchorage Zones local concrete stress simulation,results in different load combinations into the state of stress distribution of the bridge,and were to assess the safety of its structure.
