Study on Wind Loads Interference Effects of the Cross-Shaped Super-High-Rise Buildings

Abstract

There is mutual wind interference between buildings of the complex building group. For different building shapes and layout modes, the quantification of interference between buildings requires specific analysis. Based on computational fluid dynamics and the Realizable κ-ε model, this paper studies the effects of a single cross-shaped super-high-rise building and a proposed building group of four same-sized buildings at different distances and different wind directions, and obtains the wind pressure, average shape coefficient, equivalent static wind loads base bending moment, interference factor and interference variation range of base wind effect of each building group. The results show that the wind pressure on the surface of each building and the base wind parameters between buildings are more significantly affected by the wind direction than the building spacing. The effect of the building equivalent base wind is affected by the wind interference effect. It provides reference for wind resistance design of high-rise buildings with complex section.
