|Abstract: ||The conflicting demands connected from a side to the crossing of span always longer and from the other to the containment of the environmental impact of the structures set the necessity to critically re-examine the designing aspects that has brought to define the actual standards for the realization of long span cable bridges. In the case of fan-shaped scheme with "H" towers, the analysis of the statical behaviour of such structures through analytical approaches in closed form is currently founded on continuous models where the interaction between the girder and the cables is modeled through the Dischinger's tangent theory, that is through a first order approach in the displacements. In the case of non too long span, such approach allows to model in a satisfactory way the intrinsic non linear behaviour of such structures, connected to the presence of complexes structural elements as cables.
On the other hand, when the spans become meaningful, the effects of interaction cable-girde...|
