摘要

针对高速公路多联连续梁桥的抗震问题

本文对铅芯橡胶支座和摩擦摆支座进行了隔震效应分析与设计优化。本文基于多联有限元模型和非线性时程分析方法

分析了多联体系下各墩地震响应的差异

及铅芯橡胶支座和摩擦摆支座的隔震和耗能效果

并对隔震支座的参数布置进行了优化。结果表明: 多联桥梁交界墩的地震响应较联内墩一般增大20 %以上

交界墩上部结构跨径差异较大时甚至可达75 %。铅芯橡胶支座位移限制能力和大震耗能更好

且屈服前刚度越大、屈服强度和屈服后刚度越小

滞回耗能能力越强; 摩擦摆支座小震时即可发挥其隔震效果

且滑动摩擦系数越小、曲率半径越大

隔震效果越好。通过在交界墩布置更多隔震支座可在保证一定隔震率的同时改善桥墩受力不均匀的问题

具有一定的工程参考价值。

Abstract

This study focuses on the seismic isolation analysis of highway multilink continuous girder bridges and optimization of the lead-core rubber and friction pendulum bearings. The variations in seismic response among piers were examined first using nonlinear time history analysis of multilink finite element models. The seismic isolation and energy dissipation capabilities of lead-core rubber and friction pendulum bearings were then evaluated and compared. In the end

the parameters and layout of the isolation bearings were optimized. The results reveal that the seismic response of the junction pier between adjacent links is generally higher than that of the inner piers by approximately 20 % and can even reach 75 % when the spans above the junction pier exhibit large difference. The lead-core rubber bearing exhibits superior displacement-limiting and energy dissipation capacities during high intensity earthquakes. A larger stiffness prior to yielding

along with lower yield strength and post-yielding stiffness

can enhance the energy dissipation capacity. Instead

the friction pendulum bearing can demonstrate an effective isolation effect even during minor earthquakes. A smaller the sliding friction coefficient and a larger radius of curvature lead to a better seismic isolation effect. By arranging more isolation bearings at the junction piers

the problem of uneven responses among piers can be improved while maintaining an acceptable isolation rate. This study offers considerable engineering implications.
