Earthquakes generally consist of six components: three translational and three rotational. Translational components are more easily measurable than rotational components, leaving the latter’s effects on engineering structures underexplored. Recent studies have revealed that rotational components can cause a heightened seismic response in engineering structures; however, their specific impact on tall steel buildings remains inadequately addressed. Additionally, while fluid viscous dampers (FVDs) are widely used for seismic mitigation, their effectiveness in controlling responses induced by rotational components of earthquakes has not been thoroughly investigated. With India's increasing demand for resilient tall buildings, fluid viscous dampers (FVDs) have emerged as an effective solution for dissipating seismic energy. This study focuses on the influence of rotational components of earthquakes on a 20-storey linear tall steel building (measuring 60 m in height), embedded with FVDs. The 2015 Lefkada earthquake, which has acceleration time history data along three translational and rotational degrees of freedom, is considered for the current study. The linear time history analysis is performed using ETABS. The findings reveal that the rotational components notably increase the structural responses such as lateral displacement, inter-storey drift, overturning moment, etc. However, tall buildings embedded with FVDs effectively mitigate these amplified responses, thereby enhancing structural stability.
