Wind-Induced Vibration Response Analysis of a High-Rise Structure

Abstract:

Autoregressive (AR) method can provide a simulation of random process with relatively short computational time and acceptable accuracy while Newmark-β Method is a quick way to accomplish the response analysis. Therefore in this paper, the combination of these two methods will solve the problem of wind-induced response analysis quickly and precisely. According to several theories, such as wind engineering, vibration theory and random process, we succeed to model 37-dimensional correlated random wind velocity and it is used for the response analysis. Then we utilize Newmark-β method to analyze successfully and the key results demonstrate that Guangzhou New TV Tower does not satisfy the requirements in the building code of China thus vibration control is needed.
