Aeroelastic modeling of wind loading on a cable-net supported glass wall

Wind loading study on a cable-net supported glass wall is conducted by means of wind tunnel tests.An equivalent aeroelastic model is designed and constructed.Response of displacements of the wall is measured and analyzed.In order to design a glass wall under wind loading,the"windvibration factor"is estimated and discussed.In fact,the mechanism of wind acting on the wall is commonly known not only as positive pressure,but also as negative pressure caused by the flow separation on the corners of the building.Due to the diffidence in the mechanism of wind acting,two typical response cases are classified.The results show that the dynamic response of the structure caused by the negative pressure is stronger than that of the positive pressure case. To determine the aerodynamic wind loading on a flexible part of structure on a building,wind tunnel study may be useful and play an important role.
