Internal pressures in a low-rise full-scale building

Theoretical analysis, numerical simulation and full-scale measurements were carried out to investigate internal pressures at the WERFL low-rise full-scale test building at Texas Tech. The mean and fluctuating internal pressure coefficients are small in the nominally sealed building; and increase with increasing windward/leeward open-area ratio. The effects of building flexibility on the internal pressure fluctuations are accounted for, in this study. Internal pressure fluctuations above a characteristic frequency are attenuated in the nominally sealed building. The internal pressure energy is increased close to the Helmholtz frequency, in the building with a single-dominant opening.
