采用摩擦和消能装置的加层结构振动台试验研究

Research on Shaking Table Test of Building with Added Floors and Using Friction and Energy-dissipation Devices

本文结合加层结构实际工程，提出采用摩擦阻尼器和砂垫层作为减震装置，进行了增设摩擦和消能装置的加层结构模型模拟地震振动台试验，并引入非经典阻尼分析理论对试验结果进行了分析比较。结果表明采用摩擦和消能装置的加层模型减震效果明显，摩擦和消能装置能有效地吸收地震动输入能量，减小模型结构的地震反应。

The shaking table test was performed on model of an added floor building with friction and energy-dissipation devices. The non-traditional damping theory is introduced to the analysis and the test results are compared. The results show that the friction and energy-dissipation devices are very effective in reducing the seismic response and in dissipating the input energy of model structure.
