Product Detail
1)up to 16% damping,high damping 2)no damage for high intensity earthquake 3)used in building and bridge 4)rubber project HDR

HDRB isolators fulfil the following requirements: Transmit the vertical loads due to permanent and accidental effects; Capacity to support horizontal loads due to service load conditions with very low displacements Capacity of isolate the structure by shifting the fundamental vibration period to an optimal and safe level Capacity to dissipate energy to reduce the horizontal displacement of the isolated structure with respect to the ground

HDRB isolators have the following advantages:

- No damage to the structure that remains due to the elastic response for high intensity earthquakes with no interruption of the structural function. This is a primary goal for strategic structures (hospitals, control rooms, ecc…) - Very well known and used in many applications both for buildings and bridges - Very simple maintenance mainly limited to a periodic visual inspection for all the design life - Capacity to reduce the seismic energy from the ground to the structure with consequent simplification of the structure design
