摘要：

New empirical formulae are presented for the spectra of lift and torque for square and rectangular section buildings with different side ratios and their validity and applicability are discussed comparing with experimental data in three different boundary layers. As a results, it is shown that the new empirical formulae may provide more accurate input forcing functions for preliminary design of isolated tall buildings with various geometrical conditions than existing formulae.
