Output-Only Damage Detection of Steel Beam Using Moving Average Filter

Table 1

Four damage scenarios considered in the numerical model analysis.

Scenarios	1	2	3	4
Crack depth-to-beam flange ratio	40%	30%	40%	30%
Location	At Node 5 (mid-span)	At Node 7	At Nodes 2 & 5	At Nodes 3 & 7
Name	N5D40	N7D30	N2N5D40	N3N7D30

Note. The scenarios are designated as N (damage location) D (delta). For example, N5D40 refers to a scenario where delta is 40% at Node 5, or N3N7D30 indicates the one where delta is 30% at Nodes 3 and 7.
