Abstract

This paper presents the response spectrum for Jugo, a strong wind blowing from the south-eastern quadrant over the Adriatic Sea region. The response spectrum is constructed on the basis of classical elastic and resonant response spectra of a single-degree-of-freedom (SDOF) system, which are calculated from the data of the wind force measured
at the location near Split. The spectra are constructed for different intensities of the dynamic wind force, i.e., for a wind with different average velocities. After presenting the spectra in a non-dimensional form, their reciprocal similarity can be observed irrespective of the intensity of the wind force. A non-dimensional shape of the response
spectrum for the observed wind named Jugo is constructed by a non-dimensional comparison based on the envelopes of the averaging values. It can be observed from the presented results that the ordinates of response spectra are constant. The response spectrum of the Jugo wind is compared with the response spectrum of the north-eastern Bora
wind measured at the same location.
