In the last years, important developments and innovations took place in the structural engineering context. In spite of that, most of that progress does not consider the random nature of the involved variables. Based on these aspects, a contribution to the safety and reliability analyses for building floors is presented. It is also introduced probabilistic and statistic concepts, applied to a well-known non-linear models for the reinforced concrete elements (Ghali & Favre). The concrete compression strength, as well as beam and floor displacements are assumed random variables, following a known probability distribution. The aim of the work is to relate the concrete characteristic strength in compression (fck) and the Young's modulus with certain levels of reliability, expressed by the β index and by the failure probability of the limit state function. The behaviour of the basic variables and their interactions are analysed in order to evaluate the safety reached by applying NB-1 (Brazilian code for reinforced concrete structures) and EUROCODE design recommendations. Moreover, some comments are made on the future studies required to achieve a single reduction coefficient γc for the concrete strength, which may be given in terms of the basic variables of material models and their probability distributions.
