摘要：
At the present moment a suspension bridge is the most suitable type for very long-span bridges. Increased deformability is one of the basic disadvantages of suspension bridges. Usage of prestressed suspension bridge with cable truss is a method of fixing the problem of increased deformability. A prestressed suspension bridge with cable truss with the cross web and span of 200 m was considered as an object of investigations. It was shown, that usage of cable truss for prestressed suspension bridge allows reducing the vertical displacements up to 16% in comparison with the single cable. Applying of structure with four stabilization cables instead of structure with two stabilization cables allow to reduce difference of displacements in transverse direction by 24%.
