Static And Dynamic Analysis Of Self-anchored And Single-tower Suspension Bridge

Self-anchored and single-tower suspension bridge is the suspension bridge in the shape of a new type. The traditional suspension bridge is a anchored suspension bridge and Cost higher. Self-anchored and single-tower suspension bridge is not only sleek and Strong adaptability and very close economic. Therefore, this application of bridge-shaped is very good prospects. Come with the necessary research.Combining engineering practice, this paper research and analysis on static characteristics, dynamic characteristics and structural constraint system of the self-anchored and single-tower suspension bridge. Concrete work covers the following aspects:(1) Based on the finite displacement theory and the characteristics of Self-anchored and single-tower suspension bridge, and considering the nonlinear factors. A span of 80 +190 +260 +80 m independence of the self-anchored suspension bridge tower carried out a detailed analysis. Through static analysis of the vector cross-over cable, cable-plane form, stiffening beam camber and the temperature load on the structure.(2) Based on the finite element theory, the finite element model of Daguhe Bridge is set up. Through the constant change its dead load, stiffening stiffness and tower stiffness, its vibration characteristics were analyzed.(3) In the finite element model on the basis of the self-anchored and single-tower suspension bridge, various structural constraint system for static and dynamic calculation, Comparison of the binding structure of the bridge.(4) Seismic design from the perspective of self-anchored single-tower suspension bridge structural constraint system were analyzed. Focusing on a more appropriate long-span suspension bridge seismic structure, tower, beam elastic constraint system were analyzed to study the elastic stiffness constraint on the value of the different structure of the bridge.
