| Abstrakt: |
The article presents the methodology for designing an innovative pre-stressed cable-stayed steel bridge structural system using intersecting cables and string. The behavior of this new structural system under the effect of permanent and temporary loads is also taken into account. The article also discusses the design of the components of this new type of structure and presents the calculation methodology of this structural system taking into account geometrical nonlinearity. Installation sequence variants of such a bridge are also considered as well as the influence of string and cable pre-stressing on bridge displacement and component stresses. Equations for calculating bridge string stresses and displacements are presented. The article shows how to design this new steel bridge system which is more effective than the typical cable-stayed bridge structure according to the mass criterion. |
