Title: Base isolation device
Inventor: NIWA HIROSHI
IPC: F16F15/04
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To enhance base isolation performance by offsetting the dead weight of a structure by means of fluid pressure, reducing a load applied to a base isolation device and decreasing the number of base isolation natural frequencies. SOLUTION: A plurality of elastic bodies 39 having horizontal, upward and downward actions, cylinders 42, and pistons 43 are provided between a foundation 4 and a structure 6. The cylinders 42 are installed on the foundation 4; the pistons 43 on the lower surface of the structure 6. A pressure chamber 44 is formed between each piston 43 and each cylinder 42. A compressive fluid is filled in each pressure chamber 44. The compressive fluid is pressurized so that the compressive fluid may offset the whole or part of the dead weight of the structure 6. The result relaxes dead weight burden to allow the use of elastic bodies having lower rigidity, decreasing the number of base isolation natural frequencies, resulting in further enhancing base-isolation performance.
