This paper developed simplification method of wave propagation modeling for discontinuous structure by using reflection and transmission coefficients. The discontinuity was replaced with reflection and transmission coefficients that were identified with measured data beforehand. Then new spectral element which includes reflection and transmission coefficients was derived. The element was based on the elementary theory of a bar, except for the modeling of a discontinuity part. Spectral element method based wave analysis was also performed to show the validity of the modeling. The behavior of resultant wave showed good agreement with the assumed frequency characteristic on reflection and transmission coefficients.
