摘要
为了解决高层钢结构中普通中心支撑工作性能较差的问题,以提高高层钢结构的抗震性能,本文作者设计讨论了一种摩擦型滑动消能支撑。在试验基础上,对其工作机理进行了初步探讨,分析了其恢复力特性及其影响因素。试验表明,这种摩擦消能支撑与普通支撑相比,能够耗散较多的能量,而且支撑中应力始终保持在可控制的弹性范围内。在增加结构延性和消耗能量等抗震特性方面,这种消能支撑是很有效的。
In order to improve the aseismic ability of high-rise steel buildings, an energy absorption brace device based on friction is presented in this paper.Based on the tests,the working mechanism of this device has been explored preliminarily.The working behavior, hysteretic characteristics and influencing factors are analysed. The results show that this energy absorption brace devioe can dissipate more ground energy and is very efficient in increasing the structural ductility. Another important thing is that the stress in brace can be controlled to keep in elastic stage.
