Emulational Calculation of Concrete Perfusion in Steel-Pipe Arch Rib of a Large-Span Bridge

Abstract:

Article Preview

The bridge is a half-through steel-pipe concrete arch bridge with uniform catenary. Based on sufficiently considering the principle of symmetrically loading rib concrete, the pouring process of the whole concrete is calculated with emulation with the aiding of commercial package MIDAS/Civil. By analyzing the structural deformation, stress and stability, the structural responses such as the structural distortion deformation, bearing-force characteristics and stability coefficients at different construction stages are computed in this study. The motivation of this investigation is to ensure the structural safety, and the structural security can also be discussed. The made observations indicate that the whole bridge has a high safety in either construction or operation and the achievement of research may provide reference for the similar arch bridge.
