Internal Pressure Studies

This investigation entails a comprehensive analysis of the impact of dominant variable openings on both steady and transient responses of wind-induced internal pressure in a low-rise building through a boundary-layer wind tunnel (BLWT). The study aims to explore the differences and similarities in responses between steady-state and transient scenarios, with particular attention given to the size and locations of openings and vent openings and the effects of wind angle of attack. Additionally, the necessity of internal volume correction during sudden breaching, i.e., a transient response experiment, was examined. Ultimately, this study concludes with a comparison of the BLWT data with the established standards outlined in ASCE 7 and with limited large-scale data.
