To improve structural safety under seismic excitations, a new type of active response control system which is named an 'active air-bag control system' is proposed. The argument of this paper is put on the upgrade of the system efficiency from the pilot model of the active air-bag. At first, the following two improvements are carried out as the hardware progress: 1) installing friction-less type of air-cylinders, 2) replacement of air pressure regulators into high-speed response type. By those progress, high performance of the control system is actualized. To accomplish effective aseismic response control by making the most of those progress, modification of the control algorithm is investigated. Emphases are put on the response prediction methods and the index functions. Active control tests are executed for the experimental model of the active air-bag system on the shaking table. As a result, the suitable condition of the control algorithm to actualize effectiveness of the active air-bag are assured.
