Building rounded corner edges effect on peak wind load

Abstract

The relevance of this study stems from the need to improve calculating technique for wind load on modern buildings, especially with non-standard geometry and modified corner edges. Existing regulatory documents do not fully account for the specific features of the wind pressure distribution on the buildings with rounded edges. The objective of this work is to perform a computational and experimental study of the peak wind loads on the buildings with rounded corner edges distribution. The research methods include experimental tests in a wind tunnel and numerical modeling in the ANSYS CFX software package. Three objects of various configurations were studied. It is shown that the corner edges nature significantly affects the wind loads distribution. It was established that rounded edges create an increased probability of extreme local pressures with coefficients cp=-4. Practical significance of the study lies in the possibility of more accurate predicting the wind loads distribution of at the building design. The obtained results allow making informed decisions when assigning peak wind load components, thereby increasing the reliability and safety of modern architectural structures.
