Abstract

The live load factor, as a function of the expected life-time, is computed for cast-in-place reinforced concrete elements (i.e., beam, slab and column) for a combination of dead and live loads. The accuracy of the reliability analysis is enhanced by taking advantage of the Rackwitz-Fiessler method which in turn is corroborated by Monte Carlo simulation applied to the calculation of the target reliability indices of each structural element type. As an example, the formulation of live load factor is reversed to demonstrate how the life-time or the probability of failure are affected as the actual design deviates from the requirements of the current building code.
