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。 The finite element elastoplastic method is used to simulate the five different hole sizes of three different thickness of adobe walls. By calculating the degree of anti-side bearing capacity, crack shape, load displacement curve, ductility and hole size on the seismic performance of plain adobe walls, the simplified calculation of anti-side bearing capacity of plain adobe walls formula. At the same time, the seismic performance of adobe wall under earthquake of different intensity is evaluated, and the limitation of hole size for adobe wall is proposed. The results of this study can provide reference for the reconstruction of traditional village houses and seismic strengthening.
