In this paper, the seismic damage behaviors of a large-scale cable-stayed steel bridge are investigated using refined shellmodels with the assistance of supercomputing systems. Although the number of discretized nodes and elementsgenerated by shell models is much more than those of fiber models, the computing efficiency problems of large-scaleshell models can be well overcome by using parallel supercomputing. Using the precise shell models, the local yetcritical buckling behaviors of the thin-walled members in the bridge can be well captured, which provides a moreaccurate estimation of the seismic vulnerability of the various bridge components.
