Abstract : A suspension bridge is more appropriate type of structure for extremely long-span bridges due to the rational use
of structural materials. Increased deformability, which is conditioned by the appearance of the elastic and kinematic
displacements, is the major disadvantage of suspension bridges. Prestressing can solve the problem of increased kinematic
displacements under the action of nonsymmetrical load. A prestressed suspension bridge with the spans of 50, 200 and 350
m was considered as the object of investigation. The cable truss with the cross web was considered as the main load carrying
structure of the prestressed suspension bridge. Optimization of the cable truss web by 9 variables was realized using genetic
algorithm. It was obtained, that the displacements of the prestressed suspension bridge with the proposed cable truss are
smaller by 26–30% than the displacements of the structure with the single main cable for the span interval from 50 to 350 m
in the case of the worst situated load. Many people in different branches of engineering work to build bridges. Civil
engineers are responsible for design and construction of such structures, and they work with mechanical engineers and
material engineers to design the most stable structures possible for given project restraints. These engineers must consider
many variables when creating plans, such as distance to be spanned, where the bridge is being built (physical terrain), what
type of traffic (and other loads) it must carry, materials available, budget, and what the bridge will look like. Some different
aspects in civil engineering science that are applied through civilization and in people living such as decoration and bridge
building industry, are from update cases we discuss in this research paper resulted from an annual research project.
