Internal Pressure in Real Flexible Porous Buildings with a Dominant Opening: Design Perspective
Publication: Journal of Structural Engineering
Volume 139, Issue 2
Abstract
Analytical and associated numerical investigations of the fluctuating internal pressures induced through a dominant opening in real buildings with leaky and flexible envelopes are undertaken. The damping effect of these factors both separately and in combination are quantified using RMS internal pressure coefficients and equivalent damping ratios for a range of envelope flexibilities and background porosities for the case of the Texas Technical University test building and a large-span industrial building. Simulated ratios of the RMS internal pressures and the peak spectral response of internal pressure for leaky and flexible buildings to that of rigid nonporous envelopes are presented in nondimensional format for a range of building volumes, opening areas, and porosity ratios. Additionally, nondimensional curves of the RMS internal to external pressure ratios for real flexible and leaky envelopes are presented along with experimental data reported in the literature in a form suitable for design purposes.
