Time-Dependent Structural Reliability Assessment for Nonstationary Non-Gaussian Performance Functions

In this paper, a new analytical formula is proposed to determine the mean outcrossing rate of nonstationary non-Gaussian performance functions. The performance function is firstly transformed into a standard Gaussian process using its first four moments and autocorrelation coefficient function, and the mean outcrossing rate of the time-variant performance function is then derived from the transformed standard Gaussian process and the cumulative...
