Average spectral acceleration, AvgSA, is defined as the geometric mean of spectral
acceleration values over a range of periods and it is a ground motion intensity measure …

The re-centering capability represents a fundamental property of any effective isolation
system. Indeed, a potential residual displacement after an earthquake, besides affecting the …

Ambient vibration measurements and 3-D nonlinear time-history numerical modeling are
used to assess the retrofitting measures conducted in a 6-story unreinforced masonry …

Nonstructural components (NSCs) should be subjected to a careful and rational seismic
design, in order to reduce the economic loss and to avoid threats to the life safety, as well as …

The Icelandic strong-motion dataset is relatively small and the largest recorded earthquake
magnitude is M w 6.5, whereas events of around M w 7.0 are known to have occurred in the …

Codes for aseismic design may require use of recorded ground motions as input in dynamic
analysis. When records are not available, motions must be simulated. The specific barrier …

A new configuration for passive pseudo-negative stiffness device (PPNSD) is proposed to
work as a supplemental device for the seismic protection of existing isolated buildings. The …

The paper illustrates an investigation on the effectiveness of dissipative bracing (DB)
systems for seismic retrofit of buildings with sensitive non-structural components (NSCs) and …

Loss estimation from future earthquakes is of growing importance in planning earthquake
protection strategies in high-risk areas. Loss models based on the spectral displacement …

The rocking response of structures subjected to strong ground motions is a problem of
'several scales'. While small structures are sensitive to acceleration pulses acting …
