     this paper proposes a new and simple method for estimating the collapse load of a steel cable-stayed bridge. a new convergence criterion for iterative eigenvalue computations is suggested to consider the beam–column effect of a cable-stayed bridge system. the collapse loads of two example bridges representing medium and long-span models are evaluated by the proposed method and compared to a nonlinear inelastic analysis. the results demonstrate that the proposed method is a good substitute for a complex nonlinear inelastic analysis to approximately evaluate the collapse loads as well as failure modes of steel cable-stayed bridges.
