摘要：

During strong winds, flat-plate roofs are expected to oscillate up and down. In this study, to investigate the relationship between unsteady wind forces and flow field around an oscillating flat-plate roof, first, three-dimensional forced vibration test is performed in a wind tunnel. Next, the ability of computational fluid dynamics (CFD) with an overset mesh to simulate the flow around the oscillating roof is validated by comparing numerical results with those of the wind tunnel tests. Finally, coherent structures in the fluctuating wind pressure and velocity fields around the oscillating roof, extracted using complex proper orthogonal decomposition (CPOD), are discussed. © 2019 Architectural Institute of Japan.
