The Arias intensity tensor is used to define the principal axes of seismic excitation. These axes are employed to characterize the seismic excitations and often interpret [...]

The maximum expected monetary benefit or minimum expected cost rule are often adopted in assessing the optimal seismic design levels for structures under infrequent large [...]

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 [...]
