摘　　要：应用有限元弹塑性静力方法,对3种不同厚度素土坯墙的5种不同开洞尺寸进行了数值模拟计算。通过计算分析了素土坯墙的抗侧承载力、裂缝形态、荷载位移曲线、延性以及开洞尺寸对素土坯墙体抗震性能影响的程度,并提出了素土坯墙体的抗侧承载力简化计算公式。同时,对土坯墙体在不同烈度地震作用下的抗震性能进行了评估,提出了针对素土坯墙体的开洞尺寸限制条件。此项研究结果可为村镇传统生土民居的改造及抗震加固提供参考依据。Three different kinds of thickness abode wall , with the influence of five different kinds of hole sizes, are calculated with elasticplastic FEM. Lateral resistance capacities, crack shapes, load-displacement curve, ductility as well as influence of the hole size in abode wall are analyzed. In addition, the seismic behavior of abode wall under different level intensity earthquakes action are estimated, and the limitation of hole size on the abode wail are proposed. The results of the research can be used as the reference for the rebuilding and seismic reinforcement of traditional abode residential buildings in rural.
