N2 - The use of design spectra is common practice in earthquake engineering design as opposed to wind-resisting design. Nonetheless, previous research has identified ways to map such technique to study wind effects on structures. The present investigation introduces a novel framework to deal with the dynamic performance of infrastructure subject to thunderstorm downbursts. It builds on recent developments that demonstrate that spectral analysis is applicable to wind engineering given various equivalences developed to quantify random loading generated through non-synoptic wind environment. The new framework is tested on a benchmark building via a simplified model, which demonstrates its validity. In this framework, the dynamic response of the multi-degree-of-freedom (MDOF) system subjected to non-stationary wind can be obtained assuming that the first mode of vibration is dominant when the mechanical properties of the structure and aerodynamic characteristics of the thunderstorm downburst are identified.
