What is Hanger Force Optimization in Tied-Arch Bridges about?

This document summarizes a research article that presents an efficient approach for optimizing hanger pre-tensioning forces in steel tied-arch bridges. The approach develops a load decoupling approach (LDA) to improve computational efficiency in structural analysis during optimization. LDA divides analysis into two systems - one that evaluates responses from varying hanger forces using unit load methods, and one that evaluates responses from other loads with a single finite element analysis.
