摘要
本文概述了近年来国内外高层建筑中采用的多种蠕撮技术,主要包括基础隔震、质量调频和阻尼耗能等被动控制方法。其中,尤以阻尼耗能种类较多且各有特色。作者认为摩擦阻尼耗能方法前单、工作稳定、耗能量大。是目前提高高层建筑抗震性能的最有效方法之一。文章还对今后亟需解决的一些问题提出了看法。
Many of the antivibration techniques in multi-story buildings at home and abroad are reviewed in this paper.The most commonly used passive control meth- ods,such as base isolation,mass damper and damper energy absorber are in- cluded.Among them,the last one has great variety and many characteristics. From writers'point of view,the one of the most effective antivibration methods in multi-story building today is the friction damper energy absorber,be- cause it has simple mechanism,stable behaviour and large energy absorption capaci- ty.Some problems needed to be investigated in the future are also proposed.
