Suspension Bridge Hanger Installation in SOFiSTiK

This video demonstrates a complete workflow for inserting bridge hangers force-free using CSM optimization and staged construction analysis in SOFiSTiK. Starting from the final traffic-opening state, the process shows how to determine the correct unstressed hanger lengths through targeted optimization, ensuring a straight deck and vertical hangers in the final system. The video then guides through the staged construction sequence, including activation of pylons and spans, controlled lifting of the final segment, insertion of hangers with predefined relaxed cable lengths, and subsequent lowering into the final geometry. Practical construction aspects such as lifting cables, gap closure, manual iteration versus automatic optimization, and deformation control are explained in detail. Special attention is given to avoiding unwanted normal forces at traffic opening by applying temporary geometric adjustments during construction stages. The result is a well-balanced suspension bridge with minimal deformation and realistic construction behavior, modeled efficiently and transparently in SOFiSTiK.
