Abstract: The equations of motion for two-DOF base isolation system were established and solved for the displacement transfer function.And a parameter optimization method was proposed by analyzing the amplitude-frequency characteristic of displacement transfer function.Then the formulas to calculate the optimal parameters of isolation layer were derived.A 7 floor base isolation frame was used for numerical simulation.It shows that this parameter optimization method can both reduce the seismic response of ... More
