RELIABILITY ANALYSIS OF REINFORCED CONCRETE SLABS WITH CORRODED REINFORCEMENTS

Abstract

The reliability of the design characteristics of any design is influenced by both the operating load and the wear of the material itself due to environmental influences. This article provides a probabilistic assessment of reinforced concrete elements exposed to chlorine penetration. A freely supported reinforced concrete slab was used for the study. Well-known techniques developed by many authors were included in the mathematical model of the loss of the bearing capacity of reinforcement under corrosion. Uncertainties in strength and applied load were fully accounted for using the probabilistic method. The limit state function of the bearing capacity of a reinforced concrete bending slab was developed and evaluated using the first moment’s reliability method. The whole process was implemented using the developed MATLAB program.
