Numerical Simulation of Wind Pressure Distribution on Regular Mega-Frame Surface

Abstract:

One of the critical loads in engineering design is wind load, especially for high-rise structure or multi-story structure. In order to forecast the distribution of wind effects on structure, how to accurately predict the building surface wind pressure distribution is very important. Using the wind tunnel model test and numerical simulation calculation methods, the surface wind load on the mega-frame structure were comparatively analyzed and researched in this paper. The results show that combined the realized к-ε model with the standard wall function will not only satisfy the mega-frame structure surface wind pressure value requirement, but also provide complete wind filed around, which could provide meaningful information for further research on wind load.
