Abstract

Wind loads on tall buildings equipped with innovative Porous Double-Skin Facade (PDSF) systems of various porosities were experimentally studied on a small-scale building model. The focus was on integral aerodynamic loads of a tall building equipped with PDSF systems of the 25%, 50% and 65% porosity. This structural design is highly relevant for engineering practice as it encompasses the range of the PDSF porosities that may occur in practice. The building model characterized by a smooth surface was assessed as a reference case. The analysis was performed for suburban wind conditions as a representative of atmospheric conditions characteristic of tall buildings. Wind conditions were studied at the 0° <
