✦ Synopsis

A study of the initiation of torsional response in symmetric building structures subjected to harmonic lateral ground excitation is presented. Earlier studies are extended by an examination of the importance of torsional damping as well as the distribution and geometric arrangement of the lateral load-resisting elements. In addition, the relationship between two different sets of stability diagrams derived in previous studies is clarified. Finally, the susceptibility to non-linear coupling is summarized in the form of generalized criteria, for both critical damping and the size of the regions of torsional instability, which are applicable to quite general configurations of load-resisting elements encountered in symmetric structural systems.

In the present work a geometrically non-linear model is presented to study the coupling of axial and torsional vibrations on a drill-string, which is described as a vertical slender beam under axial rotation. It is known that the geometrical nonlinearities play an important role in the stiffening of
