Proper orthogonal decomposition of roof pressure

Bienkiewicz, B. / Ham, H.J. / Sun, Y.

AbstractThis paper illustrates application of the proper orthogonal decomposition in an investigation of the aerodynamic loading on a roof of a low-rise building. Pneumatically averaged pressure in a corner region of the roof, measured for concerning wind, was used in the analysis. The pressure space covariance was employed to establish the principal modes and coordinates of the roof aerodynamic loading. These quantities were employed next to perform the modal reconstruction of the roof pressure. The convergence of the roof pressure reconstruction suggests that only a few of the principal modes and coordinates are required to represent the area-averaged roof aerodynamic loading.
