Abstract:
A method to predict the impact of errors on the reliability of reinforced concrete beams is presented. Specific equations used to determine the reliability of reinforced concrete beams with various degrees of reinforcement are summarized. These equations are utilized to measure the influence of design parameter errors on the beam's safety in bending. A computer code which generates safety sensitivity functions is discussed and its flowchart is presented. Example results are given which illustrate the code's capabilities and assess the significance of accurate prediction of the mean and coefficient of variation of each basic variable.
