Sažetak
Model experiments were performed in a boundary layer wind tunnel to study the effect of porous double-skin façade (PDSF) systems on wind loading of tall buildings. A high-frequency force balance was used to determine integral aerodynamic loading of a tall building model, and pressure transducers were employed to assess surface pressure distributions on the inner façade of the building model. The results indicate that the PDSF system yields a decrease in the maximum mean across-wind moment by ~13% regardless of the degree of the outer façade porosity, while the PDSF system negligibly affects the mean integral along-wind moment. A significant influence of the PDSF porosity was observed regarding pressure distribution on the inner façade. In particular, a low-porosity outer façade causes a decrease in peak pressures by ~10% to ~20% depending on the flow incidence angle, while an increase in the PDSF porosity does not have a noticeable effect on surface pressures on the inner façade.
