A model was presented in a previous study which provided a rational approach to deflection control of reinforced concrete two way slabs considering uncertainties in structural behavior and deflection limits was investigated thoroughly in this work. A simulation model taking into account the uncertainties in materials and loads along with sensitivity analysis of results was developed. Results of simulation represented in the form of probability density function (PDF) and cumulative density function (CDF), optimum thickness and results of sensitivity analysis of reinforced concrete two-way slab systems were presented. In this study, uncertainties in time effects (Creep and shrinkage) are taken into account by using Monte Carlo simulation and are based on proposed variable parameters taken from major references. In general, the proposed procedure results in smaller thicknesses for two-way slab-beam system than ACI 318-14 recommendations for longer spans and larger thicknesses for shorter spans.
