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

Figure 8

The smoothed acceleration signal for both damaged and undamaged beams (the damage occurred in the middle of the beam) at different locations along the beam. Blue color refers to the undamaged beam and orange color denotes the damaged beam: (a) signals from Node 3, (b) signals from Node 5, and (c) signals from Node 7.
(a) Response acceleration at Node 3
(b) Response acceleration at Node 5
(c) Response acceleration at Node 7
