摘要：

The basic disadvantage of suspension bridges can be considered their increased deformability. One of the ways to increase the rigidity of a suspension bridge is to transfer a part of stiffening girder rigidity to a suspension cable. A rigid cable better resists the imposed symmetrical and asymmetrical loads and displacements and retains its original geometric form. This paper presents a theoretical investigation of the suspension bridge with the rigid cable. Also, taking into account the geometrical non-linearity of rigid cable behaviour, a simplified analysis method for determination of forces and displacements in stiffening girder and cable of suspension bridge was developed.
