［摘要］黏滯阻尼墻在高層住宅中應(yīng)用較少，以一實際工程為例，進(jìn)行了多遇地震和罕遇地震作用分析，來說明黏滯阻尼墻在高層住宅中的研究與應(yīng)用。采用規(guī)范法和能量比法計算了阻尼墻的附加阻尼比，設(shè)定消能子結(jié)構(gòu)為與阻尼墻相連的剪力墻暗柱及梁，根據(jù)性能目標(biāo)對消能子結(jié)構(gòu)部分進(jìn)行了加強(qiáng)。分析結(jié)果表明，阻尼墻布置方案滿足目標(biāo)阻尼比，減震效果明顯，消能子結(jié)構(gòu)可以滿足罕遇地震作用下“中度損壞”的性能目標(biāo)。

Abstract:Viscous fluid walls are rarely used in high-rise residential buildings. Taking an actual project as an example, an analysis of the effects of frequent earthquakes and rare earthquakes was carried out to illustrate the research and application of viscous fluid walls in high-rise residential buildings. The additional damping ratio of the viscousfluid wall was calculated by the standard method and the energy-ratio method. The energy dissipation substructure was set as the concealed columns and beams of the shear wall connected with the viscousfluid wall, and the energy dissipation substructure was strengthened according to the performance target. The analysis results show that the viscousfluid wall layout scheme meets the target damping ratio, the damping effect is obvious, and the energy dissipation substructure can meet the performance target of “moderate damage” under rare earthquakes.
Keywords:viscous fluid wall; additional damping ratio; energy dissipation substructure; high-rise residential building
