Highlights*Practical derivation of the transfer function *In the presented method, the system matrix is independent of the number of elements *The presented method can be easily adapted to analysis in frequency and time history Acknowledgements Supports (with project numbers), name of institutions: e.g.; AFAD, TUBITAK, Governorship, Municipality, etc. AimA method is proposed to obtain Transfer functions used in one-dimensional soil amplification Location Methods MFETM method was adapted to the problem of finding transfer functions used in soil amplification analysis ResultsIn the classical finite element method, the system matrix that increases depending on the number of elements is independent of the number of elements in the MFETM method.
