N2 - In recent years, design spectra tailored to thunderstorm downbursts, revealed as a promising tool to evaluate the dynamic response on structures. The design tool merges methods commonly used in earthquake-resisting design with aerodynamic characteristics of thunderstorm downbursts and their interaction with structures. This initial step is now refined through the generalisation of the spectra, via non-linear regression modelling. The result is a multi-factorial polynomial equation that captures the influence of controlling parameters that determine the corresponding wind-structure interaction. The effectiveness of the simulated design spectra was validated through comparison with results obtained for the CAARC benchmark building when using the non-synthetic design spectra. To conclude that design spectra simulated in this way, could be used to run the standard modal analysis with the help of commercial software. The proposed model can therefore be regarded as an alternative to estimate the dynamic response on structures subjected to transient winds.
