悬索桥粘滞阻尼器参数优化研究

摘要

本文通过对悬索桥工程实例进行建模计算分析,选取7组地震波平均值,采用非线性时程分析方法,选取42种不同阻尼系数、速度指数的工况进行计算,分析对地震作用下桥梁结构的影响,为阻尼器的参数优化选取提供依据.%Based on the modeling, calculation and analysis of the suspension bridge engineering example, seven groups of seismic wave average are selected, and the nonlinear time history analysis method is used, the influence of 42 kind of working condition with different damping coefficient and velocity index on the bridge structure under earthquake action is analyzed, which provides the basis for the optimization of the parameters of the damper.
