High-damping spectral amplitudes and corresponding damping reduction factors (ƞ) are key parameters for seismic design and analysis of structures equipped with seismic p [...]

This study is focused on the statistical assessment of peak responses of structures with tuned mass dampers (TMD) or base isolation devices (BID) under seismic excitation [...]

The catastrophic nature of seismic risk resides in the fact that a group of structures and infrastructure is simultaneously excited by spatially correlated seismic loads [...]
