Abstract:
When filtered white noise is used to model ground motion, the computation of complete quadratic combination (CQC) modal correlation coefficients by integration of rational function becomes difficult, and the closed-form formulas become tedious and impractical. We propose a new method to obtain modal correlation coefficients by transforming transfer function model into state space model and then by solving a Lyapunov equation. This method can be extended to the situation where filtered white noise ground motion models are used. Kanai/Tajimi model is used to verify the correctness of the proposed method. It is not only concise, reliable and numerical efficient but also can avoid solving tedious closed-form formulas of integration of rational functions.
