Error Analysis of a Formula for Calculating Reliability Index

Zhou Jun

Abstract

A formula,adopted by the American Bridge Design Specifications,for calculating reliability index is analyzed.It is found that the formula is approximate.The reasons for errors of the formula are pointed out.Compared with the Monte Carlo Method,the formula gives the value of the reliability with an error up to 30% which goes far beyond the allowed engineering scope.Therefore the formula is not applicable to engineering.
