. "The useful life of a structure is that period of time during which the structure is able to fulfil safely its purpose, this period being dependent on (i) the material and geometry of the structure, (ii) the kind of its loading, (iii) the agressivity of the surrounding medium, etc. The contemplated project will study the role of aforesaid factors in the performance of modern thinwalled structures, special attention being focussed on fatigue and initial imperfections. The quantities characterising such initial (geometrical and material) imperfections will be treated as randomly variable parameters. Their influence on the life of structures under the action of static and dynamic loading is going to be investigated using methods of Stochastic Mechanics and in probabilistic terms, and will be aid of diagnostic analyses of both real structures and experimental models. The results obtained will be validated in the analysis of large civil engineering structures such as highway and railway bridges, towers,"@en . . "1"^^ .
