摘要

针对纯滚动隔震系统，根据其地震位移反应规律，编制了数值分析程序；采用实验方法和理论分析方法，对比分析了数值分析程序和传统的刚塑性力位移曲线方法。结果表明，数值分析程序比较合理，计算结果比较精确，且偏于保守；传统的刚塑性力位移曲线方法不合理，计算结果偏小；地震作用下，结构的最大相对位移可能超越地面的最大绝对位移。

Abstract

With the isolation system based on pure rolling as the object of study

the computer program was develeped to calculate its seismic displacement based on its characteristics. And then

experiment method and theory analysis method were adopted to analyze the new computer program and the traditional calculation method’s rationality in contrast. It is shown that the computer program is reasonable

and its results are relatively accurate and conservative. The traditional calculation method based on the rigid-plastic relation of force and displacement is illogical

and its results are relatively small. When subjected to earthquakes

the structures maximum relative displacement would be larger than the earths maximum absolute displacement.
