A probabilistic construction stage analysis using the Monte Carlo Simulation was performed to address the effects of uncertainty of the material properties. Since the creep and shrinkage equations in the material models have common influencing factors, it is reasonable to assume that the creep and shrinkage behavior of concrete are correlated by some degree rather than completely independent. Thus, probabilistic construction stage analysis by changing the correlation coefficients between the creep and shrinkage coefficients were performed and the displacement, member force were compared. Analysis results showed that the variance of total displacement increased when the correlation between the creep and shrinkage was high.

A probabilistic construction stage analysis using the SSM(Step-by-Step Method) and the Monte Carlo Simulation was performed to address the effects of uncertainty of the material properties for the construction stage analysis. Because of the common influencing factors in the material models for the creep and shrinkage, it is reasonable to assume that the creep and shrinkage behavior of concrete are correlated by some degree rather than completely independent. Thus, in this study, multiple sets of analyses by changing the correlation coefficients between the creep and shrinkage coefficients from 0 to 0.6 with an increment of 0.2 were performed, and the displacement estimates were compared. A two-bay plane frame structure was used for the example structure. Analysis results showed that the variance of total displacement also increases as the correlation between the creep and shrinkage was increased.
