Seismic damage and destructive potential of seismic events
Annals of Geophysics, 1995 This paper has been written within a research framework investigating the destructive potential of seismic events. The elastic response spectra seem insufficient to explain the behaviour of structures subject to large earthquakes in which they experience

Analysis on Seismic Damage Evolution of Seismic-Damaged CSC Columns with Strengthening
IOP Conference Series: Earth and Environmental Science, 2021 Abstract To analysis the earthquake damage evolution law, seven composite steel concrete (CSC) columns were manufactured. The experiment consisted of pre-damage loading, reinforcement with enveloped steel jackets (ESJ)/CFRPs and pseudo-static tests.

Damage identification after seismic events through damage indexes
Procedia Structural Integrity, 2023 The seismic events that have affected the building heritage over the past years have highlighted the vulnerability and the huge direct and indirect losses associated with earthquakes. The research of methodologies able to evaluate the post-earthquake damage state is clearly decisive to allow a quick and safe estimation of the building state in the ...
