钢筋混凝土摩擦耗能支撑框架-核心筒结构内力分析

摘要

The energy dissipation braces are added in two different parts of a frame-tube structure in this paper, the internal forces ofrnthe RC fraction energy dissipation braced frame-tube structure are calculated by ETABS, and the effect of energy dissipation under earthquake is analyzed. The results show that dampers couldn' t start under the action of earthquake, and could start-up under the action of severe earthquake. The RC fraction energy dissipation braced frame-tube structure can better improve the seismic performance.%对某框架-核心筒结构实际工程在两个不同的部位加设耗能支撑,采用ETABS软件,计算钢筋混凝土摩擦耗能支撑框架-核心筒结构在地震作用下的内力,分析了耗能器在地震作用下能否启动耗能和其耗能效果.结果表明,在多遇地震下耗能器不启动,在罕遇地震下耗能器启动耗能,能够较好的改善结构的抗震性能.
