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

Figure 16

Scalar values of damage index for all accelerometers at different locations and load moving velocities, as obtained from the numerical model: (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)
