| Research Abstract |
This study was aimed at developing a semi-active seismic isolator which performs to reduce the seismic response of a tall and slender structure such as the tower crane and chimney construction. For this purpose, the followings were conducted. (1) Deriving the equation of motion of very flexible beam like structure which undergoes large rotation and large deformation based on the flexible multibody dynamics. (2) Examining the seismic isolation performance of the presented seismic isolator which is composed by the parallel link mechanism and springs by numerical simulations and scaled model experiments. (3) Designing a semi-active controller which switches the stiffness of isolator to reduce the seismic response of a tall and slender structure.
