TL;DR: In this paper, a finite element computation procedure is set up for the shape finding analysis of cable-stayed bridges at different erection stages during construction using the cantilever method and two computational processes are established, one is a forward process analysis and the other is a backward process analysis.

TL;DR: In this article, a numerical method to compute the cable stays prestressing forces on concrete cable-stayed bridges to achieve the desired final geometry is presented, which includes a discrete direct sensitivity analysis module and an entropy-based algorithm for structural optimization.

TL;DR: A design methodology to predict optimum post-tensioning forces and dimensioning of the cable system for hybrid cable-stayed suspension (HCS) bridges is proposed, based on the combination of an FE approach and an iterative optimization procedure.

TL;DR: In this article, the optimal pre-tensioning design of lattice structures forming composite cable-stayed bridges was investigated. But the authors focused on the optimal use of the material composing the bridge.

TL;DR: In this paper, the Backward Algorithm (BA) is proposed to calculate the erection of cable-stayed bridges built on temporary supports, where the bridge deck is first erected on a set of temporary and permanent supports and then, the stays are successively placed and tensioned according to a predefined tensioning sequence.

TL;DR: In this paper, the Forward Algorithm (FA) that is based on the forward approach is formally presented and applied to the temporary supports erection method as no specific investigation of this erection technique has been found by the authors.
