After destructive earthquakes, objective and quantitative evaluation of building damage is significant for determine making of continuous use or reinforcement, which is the first step of recovery activities. Based on the declination of natural frequencies of building systems, damage evaluation of global buildings including soil-structure interaction can be performed. In order to evaluate building damage of inter stories rather than the whole building, in this paper, inter-story shear-wave velocities are extracted from microtremor records of a damaged 9-story SRC residential building based on the deconvolution method. A relationship between shear-wave velocity and the story rigidity of buildings is proposed. Using this relationship, the shear-wave velocities of a design example are calculated and compared with those of the damaged building. Story-by-story building damage evaluation is performed.
