Damage Characterization in Frame Structures using Output-only Modal and Feature-based Techniques

Location sensitivity of fundamental and higher mode shapes in localization of damage within a building

“…In absence of a dense array of additional sensors (which may be prohibitively expensive), post-event local inspection may be good idea to further localize the damage. Nonetheless, the mode shape-based damage signatures similar to those proposed by Panikkaveettil et al [28] can be used to narrow down whether the damage is in a beam or in a column.…”
