摘要

介绍一种用于桥梁抗震的多球面滑动摩擦隔震支座

分析这种支座的设计原理

阐明其构造特点

分析了其工作机理和滑动隔震过程

并由此建立了该隔震支座的力—位移关系恢复力模型。理论分析表明

该支座除具备完善的减隔震支座所要求的功能之外

还构造简单、隔震机理清楚、数学物理模型明确

能够满足实际应用中简单性的要求。此外

该支座在不同强度的外部激励下

可以表现出不同的阻尼和刚度。并且具备单独优化性能

即该支座可以基于多性能目标或多水准地震

对于给定的桥梁隔震系统的各个参数分别进行优化。这两种特性使得该支座适合多水准地震动作用下

基于性能的隔震桥梁抗震设计。

Abstract

A novel multi-spherical sliding isolation bearing for aseismic design of bridges is developed.The design principle

configuration characteristics

operational and sliding mechanism of this isolator is explained in this paper

and the restoring model of load-displacement relationship of this bearing is presented according to these.The bearing has perfect performance

simple structure

clear mechanism of isolation as well as explicit mathematical and physical model. It can meet the practical application of the requirements of simplicity

and

it shows smart stiffness and smart damping behavior under intensity amplitudes external excitation.Furthermore

it can optimize the parameters of an isolation system for a given bridge based on multiple performance objectives or multiple earthquake levels.These characteristics make the proposed bearing suits for performance-based seismic design of bridges for multiple levels of ground shaking.
