Abstract :
The feasibility of nonlinear control rules consisting of the conventional hybrid mass damper (HMD) method with a control force limiter and of the bounded-force control (BFC) method on an existing building, Kyobashi Seiwa Building, which is equipped with an active seismic response control system, were investigated analytically using the JMA-Kobe ground motion of the Kobe Earthquake as an input. As a result, it has been concluded that the existing system can control the responses to l0cm/s ground motion by changing only the control algorithm. The control system with 10t weight, and HMD-plus-limiter and BFC method are promising up to 50cm/s ground motion. The control force, stroke and control power requirements of the BFC and HMD-plus-limiter method were well within the practical range
