In this paper a dynamic linear model of suspension bridge center spans is formulated and three different ways of fixing the main cables are studied. The model describes vertical and torsional oscillations of the deck under the action of lateral wind. The mutual interactions of main cables, center span, and hangers are analyzed. Three variational evolution are analyzed. The variational equations correspond with the way how the main cables are fixed. The existence, uniqueness, and continuous dependence on data are proved.
