Seismic Isolators - Seismic İsolation- LDRB (Low Damping Rubber Bearings) Isolator EN 15129- EN 1337 - DIN 4141 - ASTM D 4014 - BS 5400 - AASTHO M251 - AS 5100-4
The behavior of the LDRB isolators is highly linear in shear stiffness and the damping ratio is 2 - 3% of critical damping.
There is no creep in the material and the stability of the modulus of elasticity is very good.
Advantages of LRDB insulators; they can be modulated in a simpleway and they are less affected by the factors that have mechanical behaviors.
These insulators may need additional damping elements.
