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-r ise full-scale test building at Texas Tech. The mean and fluctuating i nternal pressure coefficients are small in the nominally sealed buildi ng; 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 abov e a characteristic frequency are attenuated in the nominally sealed bu ilding. The internal pressure energy is increased close to the Helmhol tz frequency, in the building with a single-dominant opening.
