Product Description

Product Introduction
Description:
High damping seismic seismic isolators
are a series of premium, meticulously engineered components designed for seismic isolation in bridges. Developed by China Communications First Highway Survey, Design and Research Institute Co., Ltd., these isolators adhere to current national standards (GB 20688) and relevant industry norms, with insights from European standards. They are patented innovations funded by significant scientific and technological research projects at the provincial and ministerial levels. This distinguished series has successfully passed provincial and ministerial scientific and technological achievement appraisals (Shaan Ke Jian Zi [2010]) No. 097 and various certifications. Upgraded to the transportation industry standard of the People's Republic of China (JT 2009-26), they are ideal for a range of highways and municipal bridges in regions with earthquake intensities of up to 9 degrees.
Isolation rubber bearings not only fulfill all the functionalities of plate bearings but also boast exceptional isolation performance, significantly mitigating earthquake-induced damage to bridges. High damping rubber bearings, a specialized category of isolation rubber bearings, are crafted from advanced high damping rubber materials, achieving a damping ratio between 10% and 16%. While their shape and structure resemble that of natural rubber bearings, the rubber material's high viscosity allows for superior energy absorption and ductility. During seismic events, these bearings extend the structure's natural vibration period, curtail seismic forces, and utilize their energy dissipation properties to serve as effective seismic isolators, akin to lead core sandwich rubber bearings.
Employing high damping composite rubber material instead of a lead core, these bearings optimize the proportion of filling materials to enhance total damping, resulting in robust energy consumption capabilities and effective isolation reduction. High damping rubber bearings exhibit stable performance and high energy dissipation, with notable ductility. Their superior equivalent viscous damping translates to heightened energy dissipation. These bearings provide remarkable seismic isolation effects, efficiently controlling the seismic responses of isolated structures. Additionally, their compact design integrates multiple functions, offering space-saving advantages, easier construction, and a cost-effective alternative to lead core sandwich rubber bearings.
