Abstract
This study deals with the standardized transformation methods for structural reliability-based design and these evaluations by considering the mathematical approaches of reliability index for its design safety. In practice, several design variables are estimated as random variables according to the failure phenomenon. i.e. normal and/or non-normal distributions. In addition, there are correlations between these random variables. Then, we reconsider evaluation spaces as standardized space throughout some transformation methods. And we investigate some characteristics of limit state functions on various design spaces by using simulation.
