WebAug 8, 2024 · More specifically, the OWT structure was assumed to be a single-degree-of-freedom (SDOF) system excited by horizontal wind and the second-order filter was utilized to obtain filtered Gaussian white noise, which resulted in a 4D dynamic system. The FFT was utilized to convert the path integration over the state space to a convolution.

The one-dimensional integrals can be generalized to multiple dimensions. Here A is a real positive definite symmetric matrix. This integral is performed by diagonalization of A with an orthogonal transformation where D is a diagonal matrix and O is an orthogonal matrix. This decouples the variables and allows the integration to be performed as n one-dimensional integrations.
