Wind Loads on a High-Rise Building

Abstract

The paper presents an analysis of the wind effect on a building with complicated geometric shape, based on a comparison of the extreme wind pressure distribution airflow research in a wind tunnel and as a result of an analytical calculation based on standards. The main differences between the analytical and actual model of wind pressure on the buildings under study are shown. So the surrounding buildings do not allow large positive pressure to arise on the facades which is well reflected in the wind-tunnel tests and not taken into account in the regulatory calculation. Wind-tunnel tests show the presence of an end zone for positive pressure on the facades, while the regulatory calculation gives out only one value of positive pressure along the height of the facade. As a result of the study, the need for assessing the wind effect through physical or numerical modeling on newly built buildings, as well as sealing development objects, when the erected object is able to make significant adjustments both to the existing aerodynamic situation on the ground and to influence the pedestrian comfort of the territory. © Springer Nature Switzerland AG 2020.
