标准范围

本文件规定了桥梁用弹性隔震器的最低要求和试验方法，以及制造此类隔震器所用的橡胶材料。适用于为桥梁提供抗震保护的弹性隔震器。覆盖的隔离器由交替的弹性层和加强钢板组成，它们位于上部结构和下部结构之间，以提供将结构系统与地面运动解耦的灵活性和阻尼能力，从而减少隔震界面处的位移，并以隔震频率将能量从地面传输到结构中。

This document specifies minimum requirements and test methods for elastomeric seismic isolators used for bridges, as well as rubber material used in the manufacture of such isolators.It is applicable to elastomeric seismic isolators used to provide bridges with protection from earthquake damage. The isolators covered consist of alternate elastomeric layers and reinforcing steel plates, which are placed between a superstructure and its substructure to provide both flexibility for decoupling structural systems from ground motion and damping capability to reduce displacement at the isolation interface and the transmission of energy from the ground into the structure at the isolation frequency.
