Research On Sectional Concrete Cable Pylon For Self-Anchored Suspension Bridge

Based on shop drawing design of Liede bridge in Guangzhou, this thesis focuses on the problems of proper parameters determination of structural static behavior and dynamic behavior in cable pylon. At the beginning of this thesis ,the author presents detailed process of building up the integrated finite element model of bridge by BNLAS an MIDAS/CIVIL, large-scale FEM software. Based on result of cable pylon,the author designs proper steel reinforced,improving seismic performance of cable pylon.The paper firstly introduces applications of steel reinforced concrete structure at home and abroad and general situation of Suspension Bridge. Secondly, finite element model of Liede River Bridge in Guangzhou will be set up to analyze cable pylon’ capability of standing force under the circumstances of static and dynamic response. What’s more, compared the results on aseismatic experiments of Liede River Bridge with static calculation from single cable pylon model, the most disadvantages combination for bridge to stand force will be stated. Finally, processing the true and effective internal force data from the most disadvantages combination on the basis of computing theory of steel reinforced concrete, the design of tower frusta under Liede cable pylon will be deployed, as well as the following seismic advantages brought by new design.Through the analysis of the above-metioned problems,The author kNowns the method in self-anchored suspension birdge which apples to the calculation of the structural static behavior and dynamic behavior.Further more,the design of SRC is deeply understood.
