Response variability in reinforced concrete structures with uncertain geometrical and material properties

This paper presents a model for probabilistic analysis of reinforced concrete structures. The study considers the effects of structural geometric imperfections, as well as the materials' mechanical properties variability on the response of beams and columns. The finite element method is combined with the Monte Carlo simulation method. The parameters of the analysis are represented as either random variables or as stochastic fields. After several simulations, the expected values and standard deviations of the deflections and of the rupture loads are evaluated. Finally, the variability of the response of the structure is investigated
