LES of fluctuating pressures on a high-rise building influenced by windward building

Abstract

Recent development of techniques on computational fluid dynamics (CFD) has enabled us to simulate the complicated flow such as the wind around buildings. Large Eddy Simulation (LES) is expected to be adopted as an effective tool to evaluate wind load on buildings for wind-resistant design of structural frames, cladding and components. In this research, the accuracy of LES to predict the fluctuating pressures on a high-rise building influenced by windward building is examined by comparison with experimental results. Especially, focusing on the case that local peak pressure occurs, the availability of LES for practical application is discussed in view of wind-resistant design.
