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 solve the problem of poor working performance of ordinary center support in high-rise steel structures and to improve the seismic performance of high-rise steel structures, the author designed and discussed a friction-type sliding energy dissipation support. On the basis of the experiment, the working mechanism of the system was discussed, and the characteristics of its restoring force and its influencing factors were analyzed. Tests have shown that this kind of friction energy dissipation support can dissipate more energy than ordinary support, and the stress in the support is always kept within a controllable elastic range. This energy dissipation support is very effective in increasing the seismic properties such as structural ductility and energy consumption.
