Numerical Analysis of Wind Load in Wind Environment of Construction Engineering by Computational Fluid Dynamics

Abstract

This study aims to reduce the threats to urban traffic and personal safety caused by wind environment problems such as "venturi effect" and "corner effect" formed between buildings in the process of urbanization. Firstly, based on Computational Fluid Dynamics (CFD), the wind environment model is built, meshed, parameterized, and solved. Then, the 270° wind direction is taken as an example to study the influence of wind environment on different building layouts. At present, three typical building groups in the city have been numerically simulated under different working conditions. Finally, the experiment obtained the results of the average wind speed, maximum wind speed, and safety range of different building layouts in the 270° wind direction. The results show that the wind load simulation can help people to study the different wind pressures formed in different areas of the building surface when different building layout structures face different inflow wind speeds, as well as the changes in the wind speed and safe area of the surrounding wind environment. Therefore, to fully understand the wind environment and wind load characteristics of different types of building complexes under strong wind conditions is of great significance for improving the planning and design level of building complexes, reducing the impact of strong winds on building complexes, and protecting pedestrian safety.
