<p><P>PROBLEM TO BE SOLVED: To efficiently reduce a response of a building in an earthquake. <P>SOLUTION: A base isolation system for the base isolation of the building includes: a variable damper which can vary a damping coefficient for absorbing an energy of earthquake motion to a structure; a sensor which detects the vibration of the structure; a means which obtains information indicating the magnitude of earthquake occurred and information indicating the earthquake occurrence position; and a table in which information on control rules of the variable damper associated with each of earthquake occurrence areas beforehand is stored. Further, it includes: a means which selects the control rule associating with the occurrence area specified from the information indicating the earthquake occurrence position; a means which calculates the maximum velocity value of the earthquake motion input to the structure from the information indicating the magnitude of the earthquake occurred and the information indicating the earthquake occurrence position; a means which inputs the selected control rule, the maximum velocity value, and the output values of the sensor to calculate the damping coefficient of the variable damper; and a means which sets the obtained damping coefficient to the variable damper. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
