Iterative Optimal Sensor Placement for Adaptive Structural Identification Using Mobile Sensors: Numerical Application to a Footbridge

•An iterative and adaptive identification approach is proposed using mobile sensors.•Sensor locations for next iteration are estimated from data at current sensor setup.•Proposed method provides more accurate results than those from static sensors.•Small number of sensors are suggested when large number of iterations possible.•Otherwise a larger number of sensors needed for accuracy in case of few iterations.
