ISOSISM® isolation systems
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.

Benefits
01. Prevention of structural damage
No damage to the structure which remains in the elastic response triggered by high intensity earthquakes without disrupting the structural function.
02. Simplified overall design
Ability to reduce seismic energy from the ground into the structure, which simplifies the structural design.
03. Versatility
New construction or retrofit purposes
04. Maintenance free
Limited to periodic visual inspection throughout the design life
05. Taylor made
Optimized design to project specifications
06. Certified products
Compliance with all international standards, CE marking on request
07. Cost savings
The overall cost of construction and/or maintenance and/or repair is significantly reduced. Structures remain operational after an earthquake, limiting operational losses and reconstruction costs.
