摘要：The present method of designing rectangular reinforced concrete beam is based on limit state designphilosophy which makes use of partial safety factors for material strength and load. The design variables being random,it becomes much more important to assess the level of safety in the probabilistic design situation. Beam being the vitalmost structural element, the probability of failure of a beam is linked to the overall safety of a structural system. Withthis in view, an attempt is made to assess the safety levels in terms of reliability index and probability of failure of thebeam. A reinforced concrete frame is modelled in ETABS software, the moment and area of tension reinforcementvalues are extracted from the same software for statistical analysis. Resistance statistics for rectangular reinforcedconcrete beam are generated using the equations provided in IS 456-2000 code. The variables relating to geometry,material properties and loading are considered as random. Probability of failure is obtained by Monte Carlo Simulationtechnique which establishes the statistics of safety margin that is Resistance(R) > Action (S). The study investigates thereliability index and probability of failure of the rectangular reinforced concrete beam and plotting of the histogram andprobability distribution curve. The entire reliability analysis was implemented through developing a program inMATLAB software.
