高阻尼隔震橡胶支座在城市高架连续梁桥中的应用

The application of high damping rubber bearing in urban viaduct continuous beam bridge

介绍了城市桥梁抗震设计的要点,结合减隔震设计的概念及主要功能,分析了高阻尼橡胶支座的工作原理,并探讨了减隔震支座在城市高架桥梁中的受力性能,指出高阻尼减隔震支座可以延长结构使用周期,降低地震力,使桥梁结构受力更加合理。

This paper introduced the key points of city bridge seismic design,combining with the concept and main function of seismic isolation design,analyzed the working principle of high damping rubber bearing,and discussed the mechanical properties of seismic isolation bearing in city viaduct bridges,pointed out that the high damping isolation bearing structure could prolong the use cycle,reduced the seismic force,made the bridge structure stress more reasonable.
