Reliability Index in ABA Design Code

ABA design code increases the reliability of a structure by means of multiplying the partial safety factors by load and resistant. In this paper, the reliability index of code-based designed structures are calculated and investigated. Also it is shown that the different values of reliability index are calculated for the different values of the coefficient of variation. This result expresses the importance of the code design collection on basis of reliability theory. In other words, the partial safety factors of design parameters for ABA must be calculated on basis of the local statistical data(in favor of Iran) of the parameters.
