Nonlinear dynamic analysis, such as a nonlinear FEM, is essential in earthquake engineering. Nonlinear analysis, which must be conducted in the time domain, sometimes suffers from computational instability triggered by high frequency noise. Authors proposed a time integration scheme that eliminates high frequency noise by a digital filter (DFTI scheme). Its computation process is a combination of conventional time integration methods and digital filtering technique. In this paper, detail of the characteristics of DFTI scheme is investigated, taking central difference method and Newmark β method as examples of time integration schemes. Investigation reveals that it does not improve the stability of central difference method. It is also found that its applicability for Newmark ?A method is limited.
