Product Description

Product Introduction
Description: 
High damping seismic seismic isolators are a series of standard components for seismic isolation bridges developed by China Communications First Highway Survey, Design and Research Institute Co., Ltd. in accordance with current national standards (GB 20688) and relevant industry norms, while referring to European standards. They are patented technical achievements funded by major scientific and technological research projects at the provincial and ministerial levels. This series of products has passed the provincial and ministerial level scientific and technological achievement appraisal (Shaan Ke Jian Zi [2010]) No. 097 and related certifications, which have been upgraded to the transportation industry standard of the People's Republic of China (JT 2009-26), are applicable to various types of highways and municipal bridges in earthquake intensity areas of 9 degrees and below.
Isolation rubber bearings not only have all the performance of plate bearings, but also have good isolation performance, which can effectively reduce the damage caused by earthquakes to bridges. High damping rubber bearings are a type of isolation rubber bearings, which are made of high damping rubber materials and can achieve a damping ratio of 10% to 16%. Its shape and structure are the same as natural rubber bearings, but its rubber material has a high viscosity, can absorb energy on its own, and has great ductility. It can extend the natural vibration period of the structure during earthquakes, reduce seismic forces, and use its energy dissipation characteristics to play a seismic isolation role, achieving the performance of lead core sandwich rubber bearings.
Using high damping composite rubber material instead of lead core, adjusting the proportion of filling material to change the total damping, making it have strong energy consumption ability, and achieving the effect of reducing isolation. High damping rubber bearings have stable performance, strong energy dissipation and ductility. High damping rubber bearings have higher equivalent viscous damping, which means they have higher energy dissipation. They have significant seismic isolation effects and can effectively control the seismic response of isolated structures. Due to the integration of functions, the volume is smaller than that of lead core bearings, which can save usage space, make construction more convenient, and the price is also cheaper than lead core sandwich rubber bearings.
