Abstract
Compared to other structural systems, cable-stayed bridges are marked by their exceptional architectural appeal. However, these bridges have several disadvantages – their deformability under asymmetrical or local loads the relatively significant mass of stiffening girder and the pylons. A successful way of stabilizing the bridge’s initial form could be using additional stay cables and additional pylons. The article discusses the calculation method of an innovative cable-stayed steel bridge system consisting of intersecting cables and additional intermediate pylons. The system’s behavior is analyzed under symmetrical and asymmetrical loading. The calculation method results are compared to the numerical analysis using the FEM software.
