An Empirical Expression for Reliability Index of Flanged RC Beams in Limit State of Deflection

摘要

Reliability indices of reinforced concrete flange beams with respect to limit state of deflection designed as per the provisions of IS 456:2000 are found to be nonuniform. Through this paper, an attempt has been made to propose an empirical expression for reliability index of a flanged RC beam in limit state of deflection. This equation will be useful in deciding depth of member for a given span, load with target reliability index in limit state of deflection and also to obtain an estimate of reliability index of the designed RC beam.
