TL;DR: In this article, the first three modes of vibration of a nineteen-story building about the two major translational axes and the torsional axis of the building were determined by random wind excitation.

TL;DR: In this paper, a simple theoretical model was used to calculate the frequencies of vibration of the buildings; the model was based on the assumption that there was no joint rotation in the building frames.
