摘要
设计制作了一种活塞式常摩擦力阻尼器,并进行了理论分析,在此基础上设计制作了一个5层钢框架模型,在其第1层、第3层和第5层薄弱层分别设置摩擦阻尼器支撑,进行了罕遇地震和多遇地震下的振动台试验。试验结果表明,摩擦阻尼器能够有效地控制结构的地震反应。
A piston friction damper was made up. The hysteretic behavior of friction damper was studied through numerical analysis. A five-floor steel-frame model was designed and constructed, which was equipped with friction damper in its first, third and fifth layers respectively. Vibrating table tests simulating the minute and disastrous earthquakes were conducted. The test results showed that the friction damper were effective in attenuating seismic response of the frame model.
