摘要
以农村地区现存的传统夯土类住宅为研究对象,根据其结构构造特点建立了有限元分析模型。通过对两种常见结构类型的静力分析、结构振型频率计算以及地震反应分析,探讨了该类结构在荷载作用下的受力变形特点,找出了结构的薄弱部位并提出了相应的改进意见,为此类建筑抗震性能的提升提供参考。
In this paper,the residential rammed earth buildings which are existing in rural area are taken as the research object.According to the texture and structure of the buildings,a finite element model is established.Through the static analysis,the calculation of the vibration mode and frequency,and the seismic response of two common structure type,the force and deformation characteristics of rammed earth construction under load action are discussed,and the weak parts of the structure and make corresponding improvements are found out.These will provide a reference for improving the seismic behavior of these buildings
