- Abstract
Due to the complexity of crosswind loads, only a few national codes/standards in the world provide calculation formulas. The high frequency force balance (HFFB) technique was used to get the across-wind base moment coefficients and power spectra by assessing the rigid models of 71 typical rectangular tall buildings under 4 different categories of terrain roughness. The effects of terrain roughness, side ratio and aspect ratio on the non-dimensional across-wind base moment spectra and RMS values of across-wind base moment coefficient are analyzed. The main parameters of non-dimensional across-wind base moment power spectra and RMS value of across-wind base moment coefficient are derived by using the nonlinear least squares method, and the error analysis of the fitted formula are studied. The accuracy and applicability of the formula are verified by comparison with wind tunnel test results and literature data. Using other parameters in the wind load codes/standards, the across-wind equivalent static wind load of typical rectangular tall buildings can be calculated by the empirical formula.
