A novel numerical analysis of fine discretization was used to investigate the response of beam under aperiodic excitations. The aperiodic excitations turned into the superposition of a series of periodic excitations in a tiny time interval. The method of harmonic response analysis was applied in the solution of aperiodic steady response. The algebraic algorithm of direct steady-state analysis can improve computational efficiency. The defect that the steady-state solution can be gotten out until the free vibration attenuates is avoided. The examples show that the numerical results match well with the analytic data.
