The traditional way to obtain the w

The traditional way to obtain the wind velocity felt by the train is to interpolate from the windspeed time histories simulated for the static points on the bridge. This method has explicitphysical significances, and the efficiency has been greatly improved in the past few yearswith the efforts of the researchers. However, Wu et al. (2015) indicated that the artificialsegmentation will lead to discontinuity problem of the wind histories for vehicles when thedistance is longer than 10 m between two adjacent simulation points. Consequently, numberof simulation points was raised up to narrow down the interval between two simulationpoints, which placed high emphasis on the computational efficiency of the multivariatestochastic process algorithm.
