Product Introduction
Description:
High Damping Seismic Isolators
Our high damping seismic isolators are meticulously crafted as a series of state-of-the-art components dedicated to seismic isolation for bridges. Developed in collaboration with the China Communications First Highway Survey, Design and Research Institute Co., Ltd., these isolators adhere strictly to the current national standards (GB 20688) and relevant industry norms, while also incorporating European standards. These patented technical marvels, supported by major scientific and technological research initiatives at both the provincial and ministerial levels, have successfully passed rigorous scientific and technological achievement appraisals (Shaan Ke Jian Zi [2010] No. 097) and related certifications. Upgraded to meet the transportation industry standards of the People's Republic of China (JT 2009-26), these isolators are ideal for a diverse range of highways and municipal bridges in seismic zones with intensity levels of 9 degrees and below.
Our isolation rubber bearings boast all the exceptional performance characteristics of traditional plate bearings, enhanced with superior isolation capabilities to mitigate earthquake-induced damage to bridges. Crafted from high damping rubber materials, these bearings achieve an impressive damping ratio of 10% to 16%. Their design mirrors that of natural rubber bearings, but with a high viscosity rubber material that independently absorbs energy and exhibits remarkable ductility. By extending the natural vibration period of structures during seismic events, these bearings effectively reduce seismic forces and leverage energy dissipation to provide unparalleled seismic isolation, akin to the performance of lead core sandwich rubber bearings.
Our high damping rubber bearings, innovatively utilizing high damping composite rubber material in place of lead core, allow for the adjustment of filling material proportions to modulate total damping. This results in exceptional energy consumption abilities and reduced isolation effects. These bearings showcase stable performance, robust energy dissipation, and impressive ductility. With higher equivalent viscous damping, they excel in energy dissipation and deliver significant seismic isolation benefits, effectively controlling the seismic response of isolated structures. The integrated functionality enables a more compact volume compared to lead core bearings, which conserves space, simplifies construction, and offers a more cost-effective solution than lead core sandwich rubber bearings.
