CHARACTERISTICS OF WIND INDUCED RESPONSES AND EQUIVALENT STATIC WIND LOADS OF TALL BUILDINGS

Computational methods and representative characteristics of wind induced responses and equivalent static wind loads of tall buildings are discussed in detail.The responses and equivalent static wind loads are both divided into mean,background and resonant components,and the formulas for these components are given correspondingly.The difference between QML and LRC approaches for background component is then discussed.A simple and convenient method for total equivalent static wind loads is proposed.Finally,a typical tall building is taken as an example to demonstrate the main characteristics of the responses and equivalent static wind loads of tall buildings.
