软钢阻尼器对高层钢筋混凝土框架的减震分析

Shock Absorption Analysis of High-rise Reinforced Concrete Framework with Mild Steel Damper

简要介绍软钢阻尼器的原理和力学模型,运用SAP2000对安装有软钢阻尼器和未装阻尼器的的高层钢筋混凝土框架两种模型进行了动力时程分析,总结分析软钢阻尼器对高层钢筋混凝土结构减震作用的效果和特点.分析结果表明,软钢阻尼器能大大降低高层钢筋混凝土框架在罕遇地震下的反应,减震效果明显.

This article briefly introduced the principle and mechanical models of mild steel dampers first.Then,SAP2000 was used to make the dynamical and time-history analysis of two models of high-rise reinforced concrete framework;one is the origin structure and the other is added mild steel dampers.The shock absorption effect and characteristics of mild steel dampers were summarized and analyzed.The result shows that mild steel dampers have great effect on high-rise reinforced concrete framework by reducing the seismic response under the actions of the rarely met earthquake.The shock absorption effect is obvious.
