Structural Health Monitoring on Damage Evolution of 6 Story Reinforced Building Through Shaking Table Test
In this paper,damage estimation on damage evolution of 6 story reinforced building is shown through shaking table test.We carry out damage detection test by damaging the frame and we measure the evolution of damaging frame.Two types of identification are tried.One is a)identification using the data during damage evolution and the other is b)identification using the data of before and after damage.From the results of a),natural frequency and story stiffness decreases and damping ratio increases as amplitude increases,and natural frequency and story stiffness tend to be smaller and damping ratio tends to be larger during principal motion.Tendency of identified story stiffness from b)is consistent with visual inspection.Minimum identified stiffness from a)agrees with the results from push over analysis.Identified stiffness from white noise shaking which is carried out just after earthquake shaking is three times larger than minimum identified stiffness from a).By using the assumption of Takeda-model,maximum drift estimation from white noise shaking data is tried.
