This paper aims at featuring dynamic characteristic of cable-stayed bridge by means of an artificial filter bank(AFB), for the purpose of effective acquirement of real-time valid dynamic(acceleration) responses. The AFB was embedded into a wireless sensing system. Also, through modal testings performed on a model of cable-stayed bridge, its dynamic characteristics were featured on natural frequency. They were evaluated in comparison to wired measurement responses and FE analysis. Finally, the dynamic wireless measurement system on the basis of AFB were found technologically and economically effective by obtaining valid dynamic(acceleration) responses whose size was compressed over the frequency range of interest.
