摘要
以一个10层单跨框架结构作为算例,利用ANSYS程序分析了摩擦耗能支撑在局部楼层中的不同设置方式对结构减震效果的影响。结果表明,在3种设置方式中,底部5层设置方式对结构地震反应的控制效果最好,故耗能支撑宜布置在层间位移较大的下部楼层。
In this paper a ten-story frame structure is used as an example. The influence of different distribution of friction energy dissipating braces in partial stories on the suppressive effectiveness of structure vibration is analyzed by ANSYS finite element program. The analysis results show that among three forms the seismic vibration control of installing dissipating braces in the five stories of the bottom is the best. It is suit that the energy dissipating braces are installed in the bottom of the frame where the response of displacement between two stories is bigger.
