高层框架-核心筒结构加设粘滞阻尼器的抗震分析
首发时间:2011-12-06
摘要:本文以武汉某框架-核心筒结构为实际工程背景,对粘滞阻尼消能减震体系在该建筑中的应用进行分析和研究。采用有限元软件建立计算模型对该工程进行动力时程分析,通过无控结构和消能结构的动力反应对比,研究粘滞阻尼消能减震结构的减震效果。结果表明:附加粘滞阻尼器后,结构层间位移角和层间剪力都有不同程度的明显减小,且减小幅度均匀。

Seismic Analysis of High-rise Framework-core Tube Structure equipped with Viscous Dampers
Abstract:With a certain Framework-core Tube Structure in Wuhan to be the practical engineering background, analysis and research the application of Viscous damping system in this project. Use finite element software to set up calculation model and do the dynamic time history analysis.Through the dynamic response comparison of no controlled structure and energy dissipated structure, research the damping effect of structures with Viscous dampers.Conclusion show,after equipping with Viscous dampers,There are different degree of obvious decrease in structures' layer displacement angle and interlayer shear force.In addition,the decrease amplitude is uniform .
Keywords: energy dissipation Viscous Dampers time history analysis seismic response
