【摘要】 采用ANSYS软件建立了考虑土-剪力墙结构相互作用的二维时域动力计算模型,分别考虑了不同土体、上部结构层数对等效输入的影响。根据计算结果,上述因素对等效输入的平动影响不大,但对基础的转动影响很大。特别地,桩基对基础的转动角位移影响很大。因此,分析土-结构相互作用的等效输入,应着重研究基础的转动输入。更多还原

【Abstract】 Two-dimensional dynamic model of soil-structure interaction of shear wall structures in time domain is established with ANSYS.The influence of different soils and stories of upper structures on equivalent seismic motion input is considered separately.According to calculations,the above-mentioned factors have little effect on the horizontal displacement time-histories of the equivalent input,but have great influence on the rotation of foundation.Especially,piles have great effect on the rotation angle displacement of foundation.Therefore,the analysis of equivalent input of soil-structure interaction should be focused on research of foundation rotation.更多还原
