SIMULATION OF MULTI-CORRELATED RANDOM PROCESSES AND APPLICATION TO STRUCTURAL VIBRATION PROBLEMS.

Abstract

A METHOD OF SIMULATION OF A SET OF MULTI-CORRELATED STATIONARY GAUSSIAN PROCESSES WITH ZERO MEAN IS DEVELOPED BY A TRIGONOMETRIC SERIES REPRESENTATION WITH GAUSSINALY DISTRIBUTED COEFFICIENTS.THIS MODEL BECOMES ERGODIC IF THE TOTAL NUMBER OF THE SUMMATION N IN THE MODEL IS INFINITY.EXAMPLES ARE ALSO PRESENTED FOR THE POSSIBLE APPLICATIONS, INCLUDING STREAMWISE STRONG WIND TURBULENCE, IN THE RANDOM VIBRATION PROBLEMS.(A)
