Suspension Bridges under the Action of Lateral Forces
Lateral forces, such as horizontal wind pressures, when acting on a suspension bridge are sustained by the cables and the stiffening trusses, which transmit the resulting reactions to the towers and abutments. The hangers which connect the trusses to the cables force the two loaded systems to work together so that the deformation on one system exerts its influence on the other. As soon as the bridge swings out of its vertical plane the effect of the dead and live load comes into action and tends to reduce the horizontal deflections. Consequently, a redistribution of the acting wind load follows until equilibrium is established between all acting forces.
