Application of semi-active hydraulic damper to an actual building
This paper reports on the first application of the semiactive damper system to an actual building. The advantages of this system are that it incorporates semiactive hydraulic dampers (SHDs) which need a small amount of electric power to operate, thus ensuring the effective structural control of large-scale constructions including civil engineering structures during a large earthquake. The paper first outlines the building to which the system is applied. The system consists of sensors, computers, SHDs and an uninterruptible power supply system. Described next is the structure of the SHD with a 1000kN maximum damping force. The performance test is then outlined, in which the actual damping force generated by the SHD is found to follow the command value well. This is followed by the description of an analytical model of the SHD (SHD model) that well simulates the test results. Finally, using this analytical model, the response reduction effect of the system is evaluated in a simulation analysis. As a result, the system proves to be extremely beneficial in improving the structural safety of the building and protecting its functions during a large earthquake.
