Mechanical Analysis and Study on Structural Parameter of Partially Earth-Anchored Cable-Stayed Bridge Part I: Mechanical Analysis

Abstract:

Based on a partially earth-anchored cable-stayed bridge with 1218m main span and composite beam, the mechanical analysis of this bridge type was conducted in this paper. The bridge was simulated with space pole department model, in which the beam element was used to model girder and tower, the truss element was used to model stayed-cable whose sag effect was corrected by Ernst theory. The load cases considered in analysis include: the completion state, the live load, the temperature load and other load combination. The analysis content include: the structural deformation, the structural internal force, the structural stress.
