Internal Pressure Studies

This study presents a boundary-layer wind tunnel (BLWT) investigation on the effect of variable dominant openings on steady and transient responses of wind-induced internal pressure in a low-rise building. The focus is on differences and similarities between transient and steady-state responses, the effects of size and locations of dominant openings and vent openings, and the effects of wind angle of attack. In addition, the necessity of internal volume correction during sudden breaching, i.e., a transient response experiment was investigated. A comparison of the BLWT data with ASCE 7-2010, as well as with limited large-scale data obtained at an open jet facility was carried out.
