In this article, the reliability analysis data of simply supported reinforced concrete beams are presented. Beams are structural elements that are very important in all kinds of structures namely high rise buildings, frame structures, load bearing buildings, timber structures and farm structures. The investigation was done using first order reliability method (FORM) with varying parameters such as depth, length and characteristic concrete strength. The safety index and probability of failure from the reliability of the simply supported beam with varying properties was given. The result of the model investigated shows that the formal deterministic way of measuring safety such as in factor of safety and load factor failed to put into consideration uncertainties in design like depth, length, characteristic strength etc. and therefore not consistent.
