Abstract: Transient response analysis of structures under seismic load is important in a seismic design. Most earthquake effect studies use time domain numerical integration methods. The method of reverberation ray matrix is a novel frequency domain matrix method for transient analysis of trusses and frames. Based on Bernoulli beam theory, the present work extends the reverberation ray matrix method to the case of ground acceleration loads. The calculation of a piece of steel frame subjected to the ground El Centro acceleration wave demonstrates that the method can be used to analyze the earthquake effect of structure accurately and effectively.
