Shear story structures are widely used in industrial equipment structure and building design but are often vibrated during the vibration of the ground. Ground vibration is caused by many variables such as earthquake, mechanical vibration, vehicle and human steps. As a result, a study on the vibrational response of this type of structure is important to both accuracy product and future building designs. Traditionally, finite element methods such as the ANSYS and MIDAS have been used as the primary methods of computing the response of such a structure. However, these methods yield low calculation efficiencies. In this paper, the mechanical model of a four-story shear structures is constructed based on the expanded transfer matrix method. The expanded transfer matrix of the components in the model and the total transfer matrix equation of the structure are derived, and the corresponding MATLAB program is compiled to determine the natural frequencies and response of the structure. The results of the transfer matrix are in good agreement with the results of the modal analysis.
