Overview

The cable-stayed bridge model attached to this article is described in detail in the CSiLoadOptimizer Technical Note. The main purpose of the model is to optimize the cable tensions, such that the final negative moments in the deck are within 1% of -1000kN-m. Figures 1 to 3 below present the results of the optimization.

Note that soft lateral supports are provided at the deck level to provide stability during staged construction.
