一种新型简易抗震装置及其在结构减震中的应用
|
摘要
总结了用于结构减震的多种安装形式的黏滞阻尼器;不同形式黏滞阻尼器通过放大两端相对位移达到减震的效果。在此基础上提出一种新的简易抗震装置,经过分析得到了该装置的位移放大系数,并通过时程分析和数值计算。结果表明其具有较好的减震效果。
Several kind of installation forms of viscous dampers for structural aseismic are summarized. Different forms of viscous dampers have seismic reduction effect by amplifying the relative displacement between the two ends of viscous dampers. On this basis,a new simple aseismic device is proposed. The displacement amplification factor of the device is obtained by analysis. The results show that this new aseismic device has better seismic reduction effect through time history analysis and numerical calculation.
