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

Abstract:

Based on a partially earth-anchored cable-stayed bridge with 1218m main span and composite beam, the parametric study 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: dead load and live load. The analysis content include: the girder bending moment, the girder axial force, the girder stress, the tower flexural moment, the tower axial force and the tower stress.
