    摘要:

    为了解决传统黏滞阻尼墙需要较大墙面积来提供足够阻尼力的问题,设计了一种基于杠杆的位移放大型黏滞阻尼墙。对传统黏滞阻尼墙和位移放大型黏滞阻尼墙的对比试件进行了滞回试验,检验了位移放大型黏滞阻尼墙的放大效果。将传统黏滞阻尼墙阻尼力公式中引入位移放大倍数,得到了位移放大型黏滞阻尼墙阻尼力公式,计算结果与试验结果吻合较好。对位移放大装置间隙导致的滞回曲线滑移现象进行了模拟,通过理论推导研究了间隙比对耗能降低率的影响程度。

    Abstract:

    Traditional viscous damping wall (VDW) needs large wall area to provide large damping force. In order to solve this problem, a viscous damping wall with displacement amplification lever (VDW-DAL) was proposed. Hysteretic experiment of traditional VDW and VDW-DAL specimens was carried out to verify the amplification effect of VDW-DAL. After adding displacement amplification factor into damping force formula of traditional VDW, a new damping force formula for VDW-DAL was obtained and it fit well with the experimental results. The slip phenomenon of hysteretic curves caused by gap was simulated and the effect of gap ratio on energy dissipation reducing rate was analyzed by theoretical derivation.
