    A calculation method of dynamic response of large-scale shaking table foundation, based on a mass-damper-spring mode, has been provided in this paper. The response of foundation to a harmonic or earthquake excitation, in consideration of the loading table-foundation coupling behavior, has been calcnlated. Attention has been paid to analysing the relation between the mass-ratio of loading table and foundation (T-F ratio) and the transfer function of the base.The analysis indicates that the foundation natural frequency falls in the working frequency range of the shaking table, such that the resonant vibration of the foundation should be estimated. It is important to properly select the T-F ratio and the foundation stiffness. The working frequency range of shaking table and the vibration limitation to the foundation as well as the rocking or rotation effect of table-foundation should be all taken into consideration in system design. The method presented in this paper has resulted in a desirable design for the 2.9m×2.9m shaking table foundation in the Institute of Earthquake Engineering, China Academy of Building Research.
