What is Actual Seismic Response Controlled Building with Semi-active Damper System about?

This paper presents the "rst application of a semi-active damper system to an actual building. The Semi-active Hydraulic Damper (SHD) can produce a maximum damping force of 1000 kN with an electric power of 70 W. It is compact, so a large number of them can be installed in a single building. It is thus possible to control the building's response during a severe earthquake, because a large control force is obtained in comparison with a conventional active control system. This paper outlines the building, the control system con"guration, the SHD, the control method using a Linear Quadratic Regulator, the response analysis results of the controlled building, and the dynamic loading test results of the actual SHD. The simulation analysis shows that damage to building can be prevented in a severe earthquake by SHD control. The dynamic loading test results of the SHD are reported, which show that the speci"ed design values were obtained in the basic characteristic test. The control performance test using simulated response time histories, also shows that the damping force agrees well with the command. Finally, it is con"rmed that the semi-active damper system applied to an actual buildin
