摘要

In this article, an acrosswind equivalent static wind load model for rectangular shaped tall buildings were proposed based on wind tunnel data. In the proposed acrosswind force spectral model, specific physical meanings are given to the key parameters. In such a way, the empirical model is more in line with current understanding on building acrosswind loads, it can be improved by others with support of additional data. The lift coefficients and spectral estimates produced by the proposed model were compared with wind tunnel measurements with satisfactory results. A large number of prototype tall buildings were used to study the model performance in term of building overturning moment. For most cases, the base moment yielded by proposed ESWL model are either within 10% error bound or slightly conservative.
