Optimization of Pre-Tensioning Cable Forces in Highly Redundant Cable-Stayed Bridges

Abstract: Cable-stayed bridges have been developing rapidly in the last decade and have become one of the most popular types of long-span bridges. One of the important issues in the design and analysis of cable-stayed bridges is determining the pre-tensioning cable forces that optimize the structural performance of the bridge. Appropriate pre-tensioning cable forces improve the damaging effect of unbalanced loading due to the deck dead load. Because the cable-stayed structure is a highly undetermined system, there is no… Show more

“…Classical methods for multi-objective optimization often involve transforming the problem into a single-objective optimization problem, which can be accomplished using well-established algorithms for single-objective optimization. The linear weighting method, for example, requires determining the weight coefficients of each objective function, where different coefficients can significantly affect the optimization outcome [9][10][11][12] . Similarly, the objective planning method requires establishing reasonable values for each objective value, while the constraint method necessitates determining the range of values for each objective function other than the main objective.…”

“…The tensioning control of cable-stayed cables is a key step in the construction process of cable-stayed bridges. The tensioning method of cable-stayed cables and the accuracy of cable force control directly affect the construction safety of cable-stayed bridges, the line of the bridge and the reasonableness of the stress state (Lam and Kang, 2022;Shan et al, 2021a, b;Asgari et al, 2015). In cantilever construction of long-span cable-stayed bridges the stressing sequence of stays is fundamental for establishing the final configuration of the bridge (Granata et al, 2018).…”
