Description:
Experience Unparalleled Safety with Our High Damping Seismic Isolators
Our seismic isolators are a groundbreaking series of standard components purpose-built for seismic isolation in bridges. Developed by the prestigious China Communications First Highway Survey, Design, and Research Institute Co., Ltd., these isolators strictly adhere to the current national standards (GB 20688) and relevant industry norms while drawing inspiration from European standards. Backed by patents and funded by major provincial and ministerial scientific research projects, these products have received appraisal for scientific and technological achievements at the provincial and ministerial levels (Shaan Ke Jian Zi [2010] No. 097). Additionally, they boast various certifications and have been upgraded to meet the transportation industry standards of the People's *** (JT 2009-26). Perfectly suited for highways and municipal bridges situated in earthquake-prone areas with intensities up to 9 degrees, our seismic isolators represent the pinnacle of engineering and safety.
Our Isolation Rubber Bearings are engineered not only to embody all the superb performance characteristics of plate bearings but also to deliver exceptional isolation capabilities. These bearings are expertly designed to mitigate earthquake-induced damage to bridges. High damping rubber bearings, a specialized subset, are crafted from high damping rubber materials capable of achieving a damping ratio ranging between 10% and 16%. While maintaining the familiar shape and structure of natural rubber bearings, these advanced bearings utilize a high-viscosity rubber material that inherently absorbs energy and exhibits remarkable ductility. They effectively extend the natural vibration period of structures during seismic events, thereby reducing the seismic forces. Their superior energy dissipation characteristics facilitate seismic isolation, mirroring the performance of lead core sandwich rubber bearings.
Our high damping rubber bearings stand out by employing a high damping composite rubber material in lieu of a lead core. By adjusting the filling material proportions, we can finely tune the overall damping properties, resulting in an outstanding energy consumption capability and optimized isolation effect. These bearings are characterized by their stable performance, superior energy dissipation, and exceptional ductility. Offering higher equivalent viscous damping, they possess an unparalleled ability to dissipate energy efficiently. They deliver profound seismic isolation impacts and significantly control the seismic response of isolated structures. Thanks to their multifunctional integration, these bearings boast a more compact volume compared to lead core bearings, thus saving valuable usage space and simplifying construction processes. Moreover, they are more cost-effective than their lead core sandwich rubber bearing counterparts, making them a prudent choice for seismic isolation.
