The Ratio Optimization of Side to Main Span in Low-Pylon Cable-Stayed Bridge Based on Yudao River Bridge

Abstract:

This paper presents an optimization model for investigating the influence on the ratio of side to main span in low-pylon cable-stayed bridge. Based on the structural analysis theory of cable-stayed bridge and combined with engineering practical, the optimization model considered that adjusting structural internal force by means of changing the side span length. Comparing and analyzing the optimization index in the result, the reasonable ratio of side to main span to this kind of bridge can be getting.
