本文件规定了建筑用弹性隔震器的规范和试验方法，以确保高耐久性和高性能。 它适用于用于保护建筑物免受地震破坏的弹性隔震器。覆盖的隔离器由交替的弹性层和加强钢板组成。它们位于上部结构与其下部结构之间，以提供灵活性，使结构系统与地面运动解耦，并提供阻尼能力，以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 specifications and test methods for elastomeric seismic isolators used for buildings to guarantee high durability and high performance. It is applicable to elastomeric seismic isolators used to provide buildings with protection from earthquake damage. The isolators covered consist of alternate elastomeric layers and reinforcing steel plates. They 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.
