某教学楼使用墙式金属阻尼器减震设计与分析

Damping design and analysis of a metal damper used in a teaching building

墙式金属阻尼器具有耗能能力强,滞回性能好,构造简单、造价低、维护方便等优点,目前已广泛应用于建筑结构的减震控制中。以墙式金属阻尼器应用于某学校教学楼的减震设计为例,介绍了墙式金属阻尼器减震结构的分析方法;在对减震结构小震的弹性和大震的弹塑性进行时程分析的同时,还对减震结构和非减震结构的抗震性能进行了对比分析。分析结果表明附加了墙式金属阻尼器后的减震结构,与非减震结构相比层间位移角减小,达到了预期的抗震目标。

The wall type metal damping device has the advantages of strong energy consumption,good hysteresis performance,simple structure,low cost and convenient maintenance. The analysis method of shock reduction structure of wall metal damper applied to a school teaching building was introduced. At the same time,the elastic-plastic time-history of small earthquakes and large earthquakes was analyzed. The analysis results show that the damping structure with the metal damper attached to the wall decreases the displacement angle between layers compared with the non-damping structure and achieves the expected seismic target.
