Description:
Pioneering High Damping Seismic Isolators
Developed by China Communications First Highway Survey, Design and Research Institute Co., Ltd., our High Damping Seismic Isolators represent a groundbreaking advancement in seismic isolation technology. Crafted in compliance with current national standards (GB 20688), relevant industry norms, and inspired by European standards, these isolators hold patents as technical milestones funded by significant provincial and ministerial-level scientific research projects. These premium products have successfully passed rigorous scientific and technological achievement appraisals at the provincial and ministerial levels (Shaan Ke Jian Zi [2010] No. 097). Elevated to meet the transportation industry standards of the People's Republic of China (JT 2009-26), they are meticulously designed for various highways and municipal bridges in regions with seismic intensity of up to 9 degrees.
Our Isolation Rubber Bearings merge the unparalleled performance of plate bearings with exceptional isolation capabilities. These high damping rubber bearings, engineered from superior high damping rubber materials, achieve a remarkable damping ratio of 10% to 16%. Mirroring the form and structure of natural rubber bearings, these bearings boast high viscosity rubber that autonomously absorbs energy and displays excellent ductility. During seismic events, they extend the natural vibration period of the structure, mitigate seismic forces, and leverage their energy dissipation characteristics to provide superior seismic isolation, rivaling the efficiency of lead core sandwich rubber bearings.
By utilizing high damping composite rubber material instead of traditional lead core, and fine-tuning the proportion of filling material, we optimize the overall damping capacity, ensuring robust energy consumption and superior isolation effects. These high damping rubber bearings exhibit stable performance, outstanding energy dissipation, and remarkable ductility. With higher equivalent viscous damping, they deliver exceptional seismic isolation effects, efficiently managing the seismic response of isolated structures. Their integrated functions reduce volume compared to lead core bearings, offering space-saving benefits, simplified construction processes, and a cost-effective alternative to lead core sandwich rubber bearings.
