Seismic safety of valuable non-structural elements in RC buildings: Floor Response Spectrum approaches

•Seismic assessment of elements with high economic, cultural or strategic value.•Extensive Parametric study of FRS by linear and non-linear modeling of RC buildings.•Numerical Floor Response Spectra versus the most used Standard’s formulations.•Peak Floor Acceleration and Peak Floor Velocity profiles along the building height.•Stability charts to assess seismic safety of free standing objects at upper floors.
