外套增层协同减震在旧房增层改造中的应用研究

Coordination Vibration Reduction Structure of Infilled Frames Story Adding Building

介绍了使用耗能元件对既有建筑物进行加固与改造的外套增层方法 ,这种外套增层方法能使新旧结构共同工作而构成协同减震结构 ,它能有效地增强外套结构底层柱的稳定性及抗侧能力 ;同时能有效地降低主结构在地震作用下的动力响应 ,减震效果明显。是增层与抗震加固的有效结合 ,为旧房的增层改造提出了一种新的结构设计方法。

By means of setting energy dissipation link between old and new buildings,make up coordination vibration reduction structure.It can be strengthen the stability and the ability of anti side sway,and also the seismic response of effect of vibration reduction are very remarkable If can be combined the storey adding and seismic strengthening effectual,yet provide a new sericulture form for storey adding and seismic strengthening.
