Abstract
New empirical formulae are presented for the spectra of lift and torqu e for square and rectangular section buildings with different side rat ios 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 in put forcing functions for preliminary design of isolated tall building s with various geometrical conditions than existing formulae.
