Wind tunnel test and numerical simulation of wind pressure on a high-rise building

摘要

We carried out a wind tunnel test to measure cladding loads for a high-rise building of 295 m in height,which would be located in the business center of Chongqing Municipality,P.R.China.The rigid model was used to determine fluctuating local pressures on the exterior surfaces of the building.The wind tunnel test results show the critical zone of wind pressures on building surfaces in both standalone and interference conditions.The computational fluid dynamics(CFD)was conducted by using the FLUENT Code to compare with the wind tunnel test results,and the steady three-dimensional turbulent flow with Realizable k-ε as a turbulence model was used.The CFD results are agree with the wind tunnel test results in regards to distributions of wind pressures over a high-rise building's surfaces.
