48pcs led模条说明 - This paper introduces the development and present situation of vibration absorb technology in the world ; generally analysis the rubber - bearing ( rb ) and lrb " s operative mechanism , function and the calculation of parameter ; advance the concept of standardization to lrb ; on the basis of generally analyzing the connected factor such as the site category , the diameter of lead bar , the height of bearing , the designing carrying capacity , the span of bridge , the inherent period and the displacement of rb , determine the parameter , the absorbing vibration target , the method and the process of standardization to lrb ; then according to the two - step rule of resisting and defending earthquake , and combining with the response spectrum theory in the seismic vibration of bridge , make a lot of calculation and analysis of vibration absorb design to the real bridge collected and combined by finite element program ; at last , gives the result of standardization through diagram and explains to its usage
本论文介绍了国内外减震技术的发展和现状；综合分析了普通板式橡胶支座和铅销橡胶支座的工作机理、性能及参数的计算；提出了铅销橡胶支座标准化的概念；在综合分析场地土、铅销直径、支座高度、设计承载力、桥梁跨径、固有周期以及支座变位等影响因素的基础上，确定了铅销橡胶支座标准化的参数、减震目标、方法和过程；并根据抗震设防两阶段原则，结合桥梁地震振动理论的反应谱法，运用有限元程序对收集和组合的实桥进行了大量减震设计的计算和分析；最后以图表的形式给出了铅销橡胶支座标准化的结果，并说明了其使用方法。
