ISOSISM® isolation systems increase the fundamental period of vibration of the structure to be protected. They reduce the response to seismic acceleration, which is reduced by a factor of two to three.
The structure isolated from the movement of the ground using ISOSISM® isolation systems increases its fundamental period of vibration and reduces the response to seismic acceleration.
The effectiveness of the isolators is directly related to the horizontal stiffness and results in a significant displacement of the structure under seismic conditions. The effects of structural isolation therefore result in a low natural frequency, low acceleration, reduced horizontal forces in the structure and increased relative displacement.
