Abstract
This paper proposes a non-iterative identification method to estimate the structural parameters of existing structure subject to seismic loading. The generalized inverse matrix obtained from singular value decomposition was employed to identify the unknown parameters in frequency domain. Because of non-iterative analysis, it requires neither the initial estimate nor the calculation of Jacobean matrices. Thus, it can reduce the CPU time. In this paper, the numerical simulation was carried out to verify the validity and to grasp the basic characteristics of proposed method. Furthermore, this method applied to the observed data of shaking table model tests. From the both investigations, the validity of proposed method was confirmed for the structural parameter identification.
