Webstatistical linearization methods have been primarily limited to special purpose “in-house” computer codes. The first known implementation in a general-purpose code was developed in [7] using MSC/NASTRAN. In this study, an alternative implementation of EL based on the methods developed in [8] and [9] will be used. WebJul 1, 2024 · A statistical linearization method is proposed for determining the response moment of multi-degree-of-freedom (MDOF) nonlinear systems, endowed with fractional elements and subjected to a combined stochastic and periodic excitation.Specifically, decomposing the response into a sum of a periodic and zero-mean stochastic …
