In this method, a six story finite element reinforced concrete model with concentrated plastic hinges, is decomposed into a series of single-degree-freedom substructures for interstory drift prediction. A virtual linear structural model, representing the linear behavior of the designed substructure, is utilized to generate reference response signals to obtain the tracking error of acceleration. The tracking error of displacement is subsequently estimated with the implementation of unbiased Kalman filtering approach, and the corresponding interstory drift of the objective substructure is then predicted accordingly. Four different noise conditions with signal-to-noise ratio of 20dB, 30dB, 40dB and 60dB are considered in the parametric study and the prediction performance of interstory drift, in terms of peak drift and time history, is investigated.
