摘要：
The dynamic response of 3-dimensional shaking-table foundation to steady-state forces is analyzed based on the exact numerical solution of rigid embedded rectangular foundation. A general lumped-parameter model is presented to correct the unreasonableness of traditional, dynamic foundation design method, mass-spring-damping model, whose spring and damping coefficients are constant in the whole frequency band. Because the dynamic stiffness matrix of foundation is frequency-dependent, the precision of general lumped parameter model introduced in this paper is better than that of the traditional method. And the result shows the general lumped parameter model can be applied in dynamic foundation design.
