Abstract
Application of autoregressive (AR) modeling in study of the results of proper orthogonal decomposition (POD) of wind-induced pressure on a low-rise building is described in the paper. The POD principal coordinates (PC) were obtained for point pressure measured simultaneously at 495 taps on the surface of a model of a low-rise building. The AR models were next fitted for the first four PC, and they were compared with the AR models developed for point pressure at representative taps on the building windward wall and roof. It was found that the order of the AR required for the principal coordinates was relatively low, and it did not exceed the order of the AR established for the considered point pressure.
