The influence of aerodynamic effects on the supporting structure of high-rise buildings depending on their cross-sectional shape

Abstract

The influence of aerodynamic influences on the load-bearing structure of RC elements: columns, slabs and beams in high-rise buildings, is an important issue during the design of modern buildings, especially in the context of rapid urban development. Using the example of seven models of cross-sections of a building with a height of 75 meters, a detailed analysis of the work of eight selected reinforced concrete columns located in the central part of the build-ing, was carried out. The analysed building models differed in the shape of the cross-sections. Static calculations with aerodynamic simulation were performed in Autodesk Robot Structural Analysis Professional 2024. Based on these, the final results of the selected one corner rein-forced concrete column are presented, giving the maximum and minimum values of axial forc-es and displacements of the column axis over its entire height on the diagrams.
