Abstract

The numerical methods are widely adopted tool for simulation of wind histories. The most accurate technique is the wind tunnel test, but it is not the most economical option. Therefore, a lot of researches are concerned with developing those methods to be more accurate, applicable, and to save executed time of analysis. This paper is concerned with comparing two algorithms for simulation of stochastic stationary Gaussian processes. These algorithms are autoregressive method (AR) and spectral representation method (SR). For the implementation of the simulation methods, a MATLAB program is built for the two algorithms.  The application of both methods is carried for using a cable stayed bridge having 670 m as a main span to study a set of points along the deck. The comparison between obtained results for both simulations is proposed. The statistical properties are calculated to compare and assess the results of both methods accurately. It is noticed that the simulated auto/cross-correlation functions of the simulated wind forces in two methods have good conformity with the target functions. Otherwise, SR method is more accurate than AR method, but the executed time in SR method is more than AR method. The research also, applied the accurate method to generate wind speeds for a cable stayed bridge to calculate the buffeting force.
