摘要
从材料的角度出发,为深入探讨采用高阻尼混凝土的结构的动力响应问题,以12层框架剪力墙结构为例,运用大型有限元分析软件ANSYS,对采用高阻尼混凝土的不同方案建立了三维有限元模型,分别进行了模态分析和时程分析,并对计算结果进行了比较,有限元分析表明：高阻尼混凝土结构的动力特性较普通混凝土结构有了显著的改善,而且当高阻尼混凝土仅用于结构的框架中时,其改善效果与整体结构都使用高阻尼混凝土的效果比较接近。
To begin with the material aspect, in order to explore the dynamic response of high-damping concrete, with 12-story frame-shear wall structure as the case, applying large-scale finite element software ANSYS, it establishes three-dimensional finite model for different programs applying high-damping concrete, and carries on model analysis and time-history analysis, and compares the calculation results. The finite element analysis shows that： the dynamic property of high-damping concrete structure is improved higher than that of the common concrete structure. Meanwhile, when the high-damping concrete is only used in frame, its improving effect and overall structure are close to high-damping effect.
