In this paper we suggest some algorithms for the fluid–structure interaction problem stated using a domain decomposition framework. These methods involve stabilized pressure segregation methods for the solution of the fluid problem and fixed point iterative algorithms for the fluid–structure coupling. With one single loop the solution of the coupled system tends to one of the strongly coupled monolithic systems. These coupling algorithms are applied to the aeroelastic simulation of suspension bridges. We assess flexural and torsional frequencies for a given inflow velocity. Increasing this velocity we reach the value for which the flutter phenomenon appears. Copyright © 2007 John Wiley & Sons, Ltd.
