【Abstract】 An identification procedure is proposed to identify story damping and stiffness parameters for flexible buildings by using ambient vibration through substructure analysis technique and statistic-average technique. It is shown that employing the relationship between the structural rotation and lateral displacement yields the feasibility of the approach presented in this paper. The effectiveness and the noise-resistance property of the approach are discussed by a numerical example.更多还原
