A two-stage damage detection scheme with vertical and horizontal searching is proposed for multi-story buildings with eccentricity. Firstly, the vertical damage searching is performed to pinpoint damaged stories and evaluate their damage extent by using ARMA model and inverse perturbation. Secondly, the horizontal damage searching is carried out to pinpoint damaged frames and evaluate their damage extent by using ARMA model and inverse perturbation. A series of shaking table tests of a torsionally coupled stuructural model are performed for white-noise and harmonic excitations. Damage states are reproduced by replacing original members by new members with smaller cross section. Based on the results, the effectiveness and limitation of the proposed damage detection method are discussed.
