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

Figure 17

Scalar values of the damage index for all accelerometers at different locations and load moving velocities, as obtained from laboratory test data: (a) case N5D40 (velocity = 0.3 m/s), (b) case N7D30 (velocity = 0.3 m/s), (c) case N5D40 (velocity = 0.4 m/s), and (d) case N7D30 (velocity = 0.4 m/s).

(a) N5D40, speed 0.3 (m/s)

(b) N7D30, speed 0.3 (m/s)

(c) N5D40, speed 0.4 (m/s)

(d) N7D30, speed 0.4 (m/s)
