Abstract

The equations governing wind-induced internal pressure responses for a two-compartment building with a dominant opening and background porosity were derived. The unsteady form of the Bernoulli equation, the law of mass conservation, and adiabatic equation were used for the derivation. The precision of the governing equations was verified by a wind tunnel test on a rigid model of a low-rise building. The results show that the governing equations can effectively analyze the wind-induced internal pressure responses. The internal pressure responses in both compartments are suppressed due to the additional damping provided by background porosity. The responses of internal pressure in both compartments, especially in the compartment without an external opening, decrease with increased lumped leakage area.
