%X First a brief introduction about nonlinear analysis of structures and its implications on their design is given. Then a description of an already built structure, namely a cantilever roof for a toll station in the motorway Tarrasa-Manresa, composed by cables stiffened by prestressed  is presented.  The static analysis of the structure, that is modelled as a plan frame, is carried out in order to evaluate its response during the service and ultimate load states. In the assumed Ioading combinations the self weight, dead load, snow load and wind actions are included. The obtained results have been admissible in accordance to the design conditions and they have been in good agreement with the results found in the original design of the structure. In the initial design analysis the structure was modelled as a plane truss with stiffening bar effects due to the existence of traction forces.
