Check the comfort of occupants in high rise building using CFD

The influence of wind on structures is a complex subject. Bending moments, normal forces, torsion moments, stresses on cladding, comfort of the pedestrians around new building, the impact of new building on existing buildings, internal pressures and vibrations are the main effects of the wind on the structures. Vibration of the structures is one of the major effects of wind especially on bridges and high rise buildings. It could lead to major displacements, accelerations and resulting forces. Acceleration is used to check the comfort of the occupants especially in high rise buildings. Wind tunnel was the only method that can be used to determine the vibration effect by wind when the standard equations of the codes cannot be applied. In this research, Computational Fluid dynamics “CFD” has been applied for the first time to check the comfort of the occupants at Lerkendal Hotel in Norway. The hotel is the third conventional highest building in Norway. The numerical model results have been compared to those obtained by codes, carried out by others. A good agreement is achieved.
