Characterization of evolving (Local) pressure fields on a low-rise building

Proper Orthogonal Decomposition is an analytical method that allows for the representation of a stochastic field by separating space and time dependence. This technique has become quite common among researchers in the wind engineering community since it is capable of efficiently reducing the number of independent variables that are associated with flow and pressure field characterization. In the first part of this study, the method is applied to full-scale experimental data synthesis of a local pressure field on a low-rise building generated by the passage of a hurricane in the proximity of the structure; physical interpretation of the resulting pressure modes is discussed. In the second part, the potential extrapolation of pressure time histories to other areas of the structure, close to the existing sensors but not instrumented, is explored through the same approach.
