摘　　要：对带暗柱的高层剪力墙结构动力性能进行研究.通过模态分析、风荷载计算和绘制滞回曲线分析带暗柱剪力墙结构在各种工况下的内力、应力和位移;在设计参数基础上,改变截面配筋率,研究暗柱结构的破坏形态和耗能能力.研究表明,随着暗柱纵筋直径增大,应力水平和耗能能力均有不同程度的增强,带暗柱剪力墙结构动力性能相比于普通剪力墙有所提高,最后本文给出带暗柱的剪力墙承载力计算方法.In this paper,the dynamic behavior of high-rise shear wall structure with concealed columns is studied.Wind load calculation and drawing hysteretic curve,the internal force,stress and displacement of shear wall structure with concealed column under various working conditions are analyzed through modal analysis.Based on the design parameters,the method of changing section reinforcement ratio is adopted to study the failure mode and energy dissipation capacity of the structure.The finding is that the stress level and energy dissipation capacity are strengthened with the increase of the diameter of the longitudinal reinforcement of the concealed column and the dynamic performance of the shear wall with concealed column is improved compared with that of the common shear wall.
