A structural health monitoring approach to extract thepredominant hysteretic response of a building usingacceleration data was proposed by Kusunoki et al [1]. Thisinvolved: (ⅰ) applying the discrete wavelet transform todecompose signals into different ranks, (ⅱ) calculating therelative floor acceleration and displacement response foreach rank, (ⅲ) simplifying the response into an equivalentsingle-degree-of-freedom response for each rank, (ⅳ)selecting and combining ranks which contribute most to thepredominant response mode, and (ⅴ) obtain the equivalentsingle-degree-of-freedom response using the combined ranks.
