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

Figure 15

Distribution of the damage index along the beams, as obtained from laboratory tests: (a) delta = 40 at Node 5 (velocity = 0.3 m/s) and (b) delta = 30 at Node 7 (velocity = 0.3 m/s).

(a) Case N5D40 from laboratory model

(b) Case N7D30 from laboratory model
