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 elastic and kinematic displacements, is the major disadvantage of

A suspension bridge is the most suitable type for a long-span bridge. Increased kinematic displacements are the major disadvantage of suspension bridges. This problem can be solved by application of prestressed cable truss. Dynamic approach is one of

The hierarchic structure is formed by the negative Gaussian curvature type saddle-shaped cable roofs by suspending separate roof’s corners to a higher level cable structure. These systems can be inter-combined to form wider roof areas. In order to
