摘要：
Based on random vibration theory, a method is developed for wind induced lateral-torsion coupled response of structurally asymmetric tall buildings, in which the integrated effects of mode coupling and wind force correlations are also taken into account. With the wind pressures data on rectangular tall buildings measured with a wind tunnel test, the coupled responses of the rectangular tall buildings are calculated. The effects of eccentricity location and side ratio are also examined for serviceability. The results indicate that the alongwind eccentricity between centers of mass and rigidity for a building whose windward breadth is shorter than its depth may result in a great increase in wind-induced responses.
