摘要

滑移隔震结构地震反应的分析和计算可通过滑移隔震结构非线性反应谱进行简化。由于非线性体系不能采用叠加原理

参数较多

所建立的非线性反应谱比较繁琐。本文通过对滑移隔震体系地震反应方程的变换

研究了滑移隔震体系地震反应中的动力相似关系。研究表明

滑移隔震体系虽然不符合叠加原理

但通过其中的动力相似关系

任何输入幅值下滑移隔震结构的任何反应都可由某一固定输入幅值下隔震结构相应反应经修正得到

理论上这种修正是不含任何误差的。利用该动力相似关系

滑移隔震结构体系非线性反应谱可得到极大简化。

Abstract

The analysis and computation of the earthquake response of sliding base-isolation system could be simplified by inelastic response spectrum. Because superposition principle is not applicable for inelastic system with more parameters

the inelastic response spectrum is more complex. In this paper

through the transformation of the dynamic equations of the sliding base isolation systems

the kinematic similarity of the system was studied. The research indicated that though superpositon principle is not applicable for the systems

by the kinematic similarity of the system

the responses of the system under an earthquake intensity could be obtained by multiplying the response spectrum established under another intensity with modifying coefficient. In theory

the modifying coefficient is absolutely precise. Using the kinematic similarity

the inclastic response spectrum of base isolation system can be greatly simplifiedr.
