This paper focuses on the applications of POD to wind engineering of structures.
Several applications of POD to wind engineering have been studied, Holmes reviewed studies of the analysis and synthesis of pressure fluctuations of bluff bodies in complex turbulent flows using the POD technique [1], Kikuchi applied it to fluctuating wind pressure fields on high-rise building models, taking measurements at up to 500 points by using a multi-channel simultaneous fluctuating pressure measure system [2], Tamura applied it to fluctuating wind pressure fields on low-rise building models[3].
Similar to the classical modal analysis methods, reconstruction by limited number of lower modes up to Nth, where Nengineering sense and it can be approximated by: (6) The number of modes that need to be considered can be estimated by the individual proportion ck and the accumulative proportion cN, which are defined as follow: , (7) The error level of the fluctuating wind pressure reconstructed according to Eqn.6 using up to the Nth eigenvector is estimated from 1- cN expressed in Eqn.7.
