The authors have been conducting research on the evaluation of errors caused by time integration methods. They proposed, in the previous paper, a method of evaluating errors in the solution of time integration methods when the harmonic input is applied to the first-or second-order system. The method is extended, in this paper, to the case where an arbitrary forcing function is applied to the system. Based on this method, a conventional method to evaluate the error in the numerical solution of forced vibration is also proposed in this paper.
