摘要：
Study on frequency transfer characteristics of a displacement-dependent damper modeled by complex stiffness shows that it has advantage in reduction of base shear and maximum response acceleration of the superstructure of a base-isolated building compared with a conventional velocity-dependent damper such as an oil damper. To realize a displacement-dependent damper, a simple control rule to simulate the complex damping model for active or semi-active dampers is proposed.
