Investigation on Dynamic Response of Steel Tower Structure under Time-History Wind Load

Abstract:

According to the Autoregressive Model in linear filter, the procedure, which was used to transform frequency domain to time domain, was programmed to simulate time history wind load with spatial correlation at different height of the tower by dint of numerical analysis software MATLAB. And then in virtue of the finite element software SAP2000, the nonlinear dynamic analysis to the steel structural tower under the time history wind load was made to gain the time history displacement, time history velocity and time history acceleration. Finally the comparison between static wind load displacement response and time history wind load displacement response was made to analyze the error of the static wind analysis.
