框架-核心筒高层结构的消能减震设计

摘要

剪切型阻尼器作为一种新型减振装置,具有初始刚度大,性能稳定,安装方便等优点.以实际项目为例,根据项目的特点提出了剪切型耗能器的布置方案.通过弹塑性分析表明:金属剪切型阻尼器能够为结构提供有效的附加阻尼比,且在罕遇地震性能点处结构塑性铰程度均在LS(生命安全)以内,大大增强了结构的抗震性能.研究结论可为剪切型阻尼器的设计和进一步研究提供参考.%Shear panel damper has become a new damping device with the merit of great initial stiffness,stable performance and convenience in installation.This paper presents an actual project,and a structural arrangement scheme of shear panel dampers was proposed.The elastic-plastic analysis shows that shear panel dampers can provide valid added damping to the structure.At the same time,it significantly improves the structural performance under the seldom occurred earthquake by ensuring the level of plastic hinge within LifeSafe degree.The conclusion can be used as reference to the design and further research of the shear dampers.
