摩擦耗能支撑框架结构的减震分析

Vibration-suppresseing analysis of braced frame structures with friction energy dissipation devices

摩擦耗能支撑减震技术是一种行之有效的减震措施,该文利用ANSYS程序对5层摩擦耗能支撑框架、无支撑框架和普通支撑框架的地震反应进行了计算比较。结果表明:摩擦耗能支撑具有明显的减震效果,它大大降低了地震作用下结构的动力反应。

The technology of friction energy dissipating brace is effective measure in vibration suppresseing. In this paper, by ANSYS finite element program the seismic response of a five-story frame structure with friction dissipating braces is analyzed, and is compared with that of the pure frame structure without brace and the brace frame structure without friction dissipation devices. The results show that the friction energy dissipating brace has obviously vibration-suppressing effect, and decreases dynamical response of structure sharply when earthquake occurs.
