Behavior of Prestressed Suspension Bridge

A suspension bridge is the most suitable type for a long-span bridge due to rational use of structural materials. Increased deformability, which is conditioned by the appearance of the kinematic displacements, is the major disadvantage of suspension bridges. This problem can be solved by application of prestressed cable truss with two concave chords and cross web. Pylon displacements can cause significant increase of structure total displacements in main span. Prestressing losing in time decrease prestressed suspension bridge total stiffness
