摘要

This paper is concerned with the evaluation of the effects of earthquake excited rotational components of foundation motion in structures having tall structural members. The case study, presented in the paper, is a cable-supported bridge, previously studied within a simpler representation of the seismic ground motion. The study has been developed at the numerical level using a bridge finite element model that is a refined version of a well-known model part of an international benchmark for structural control. The effects of the rotational components of the earthquake ground motion could lead to an amplification of the bridge seismic response. Assessment of the extent is part of this research work.
