Probabilistic analysis of inelastic structures
Probabilistic methods for the analysis of linear elastic structures, although sometimes unsatisfactory for the purpose of reliability assessment, are well stated and codified. By contrast, when the beneficial contribution of the redistribution of stresses has to be investigated, numerical procedures of analysis are involved and the randomness of the structural response is generally investigated by simulation procedures as no probabilistic method is applicable. However, an irrational use of simulation techniques does not produce probabilistic results, but only useless numerical results. These procedures are criticized and the adoption of 'hybrid approaches' is suggested as a rationalization. Special emphasis is devoted to the dynamic analysis of inelastic structures; the problem of establishing adequate probabilistic failure criteria is also discussed.
