Abstract

This preliminary study investigates the effect of torsional components of the ground motions (TGM) on the floor acceleration response of flexible special moment resisting frame (SMRF) buildings. For this purpose, computational models of three SMRF buildings were subjected to far-field ground motions with and without TGMs. Accordingly, the effect of TGM on the floor acceleration response of torsionally rigid structures with relatively short torsional period of vibration may be significant. Furthermore, TGMs may have adverse impact on rigid nonstructural components as it can be inferred from the amplifications in floor acceleration spectra, regardless of the flexibility of the parent structure.
