ResumoA reliability analysis is described in which the sample moments of the design variables are used to define the first four moments of a function representing the condition of failure, or malfunction, in the space of the design variables. These moments are then employed in transforming the failure function to a space of a normal random variable so permitting an estimate of failure probability to be made. A four-moment Reliability Index is defined and some examples of the technique are provided. The extension of the technique to stationary stochastic processes, for time-dependent problems, is discussed, and some alternative transformation procedures are compared.
