| Abstract: | An algorithm is presented for the dynamic responses of structures. A recurrence formula for calculating the displacement and the velocity is derived by combining the theorem of impulse with the method of discretized similarity.The analyses of parameter identification with time serieses are made.For a two-degree-freedom damped system,the displacement responses are computed by means of the formula,the structural parameters are identified with system imput and output time series,and the results are accurate. |
