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 ...

Interferometric Techniques in Structural Damage Identification [PDF]
Shock and Vibration, 2012 This paper describes several interferometric techniques and their applications in structural damage identification. With that objective in mind, damaged aluminum beams with clamped-free and free-free boundary conditions are analyzed. Different damages cases are inflicted by creating small cuts perpendicular to the beams longitudinal axis, being the ...
