Description
Wu and co-authors ask which parts of a long-span cable-stayed bridge matter most for the comfort of people driving across it. Using the Linyu Yangtze River Bridge in China as their case, the 2026 team simulated traffic crossing while the bridge flexed. They then virtually softened each major component in turn: the main girder, the stay cables, and the towers.
Each component ruled a different behaviour. Cable stiffness mainly governed how far the deck sagged vertically. Girder stiffness shaped rotation at the girder ends and the jolts vehicles felt. Tower stiffness tied to overall stability-type deformation. Road surface roughness, meanwhile, dominated passenger comfort more than any stiffness change did. The authors offer the framework as a planning layer that tells engineers whether a comfort complaint points at the deck surface or at a structural part.
