Descripción
Frequently, in the professional practice during the design phase of bridges with a very evolutionary character, the phenomenon of their structural response at different instants of the useful life is not sufficiently analysed, both for vertical dynamic actions and for the seismic actions. Since the processes of shrinkage, creep and tendons relaxation interact continuously, added to the initial tendon losses and Young's modulus time evolution, there are reflected into a variation of the hyperstatic reactions and therefore into the resistant capacity for the earthquake in the piles and for the vertical dynamic action in the deck. To illustrate the analysis, it is proposed a cantilever bridge of three spans and variable height of the two piles that support the deck, that is designed using with the Spanish IAPF standard and the concrete code EHE-08. In the case of seismic analysis, it is evaluated with inelastic time history analysis (ITHA), due to the highly non-linear character of the structural response, and in the case of vertical actions with a dynamic analysis by modal superposition method.
