Initial Equilibrium State Analysis for Concrete Self-Anchored Suspension Bridge under Dead Load

Abstract:

Based on the limited displacement theory and iteration method, took into account characteristics of concrete self-anchored suspension bridge, converted effects of prestress, shrinkage and creep in concrete into equivalent loads, made use of the finite element software ANSYS, and took a concrete self-anchored suspension bridge in China as an example, the initial equilibrium state analysis for this type of bridge under static load was carried out in this paper in order to obtain main cable curve and reasonable internal force of the girder and hangers under dead load. The results showed that, the main cable curve was smooth, the distribution of the hangers axial force was uniform, and the concrete girder had certain amount of compressive stress reserves.
