Abstract

In this paper, the influences of measurement noise on wind load identification for high-rise structure are analyzed. Introducing a mast structure as an example, the wind-induced responses under fluctuating wind loads have been obtained by using finite element simulation method; and then add measurement noise for the response, high-rise structural equivalent two-dimensional dynamic wind loads have been identified through the direct load identification based on simplified model; finally, comparing the identified dynamic wind loads with real wind loads. Simulating results shows different intensity levels noise can affect the results of the identification obviously.
