摘要:	An analytical model for tall buildings’ alongwind Equivalent Static Wind Loads is proposed. The basic assumptions, procedures and the parameters used in this model are mainly based on the results of wind tunnel investigation. In this model, the mean and RMS wind pressures on the leeward face are uniformly distributed. A moment effect based correlation reduction factor for background component is introduced to amend the difference of spatial correlation between ESWL and dynamic wind load. Building mode shape and inertia force distribution are adopted in the derivation of the resonant part of ESWL. The proposed model is compared with the current Taiwan building code and the results from Finite Element analysis of two prototype tall buildings. The result indicates that the proposed model with minor adjustment can yield reasonably accurate estimation of alongwind design wind load for tall buildings.
