| 为研究预制装配式剪力墙结构中窗下墙高度对结构抗震性能的影响，本文设计了含有不同窗下墙高度的剪力墙结构模型。采用 PKPM 和 ETABS 软件分别验证和研究了结构在小震下的设计指标和大震下的抗震性能。PKPM 软件小震分析结果表明，本文设计的含有不同高度窗下墙的剪力墙结构分析模型，能够满足规范中的各类设计指标；窗下墙高度的增加会增大结构的刚度。ETABS 软件弹塑性 Pushover 分析结果表明，随着窗下墙高度的增加，结构在大震下的层间位移角有所减小；并且窗下墙高度变化，会影响结构中剪力墙损伤的分布。 |

| To study the influence of the height for window wall in precast concrete shear wall structure on the structural seismicperformance，the structures of precast concrete shear wall structure with different height of window wall are designed in this paper.Thestructural design parameters under minor earthquake and seismic performance under major earthquake are validated and investigatedbased on the numerical model established in PKPM and ETABS software，respectively.The analysis results under minor earthquakefrom PKPM software show that the designed structures with different height of window wall have reasonable design parameters，whichcan satisfy the demand of the design significations. Increasing the height of window wall will enhance the structural stiffness.ThePushover analysis results from ETABS software show that increasing the height of window wall reduces the structural inter-story drift andinfluences the damage distribution of concrete shear wall. |
