Hebei Zaoqiang Dacheng Rubber Co.,Ltd
The Dacheng LRB isolators consist of alternate layers of rubber and vulcanised reinforcement steel plates of limited thickness and a central lead core. They allow the isolation of the structure by a proper selection of the horizontal stiffness and they can dissipate energy up to 30% damping due, to the high damping capacity of the lead core. The damping value of 30% is normally the maximum damping to model the device as linear according to the international design standards.
The Dacheng LRB 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 to 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; No damage to the structure that remains due to the elastic response for high intensity earthquakes with no interruption of the structural function.
