土坯墙体抗剪承载力的改性试验研究
|
摘要
通过传统和改进土坯墙在单调荷载作用下的试验,得到土坯尺寸、改性泥浆及砌筑方式对土坯墙抗剪性能的影响,以及土坯墙裂缝的开展规律、破坏特征、承载能力、延性等力学性能。并在试验基础上,给出了传统和改进土坯墙抗剪承载力的计算公式。
Based on experimental study on traditional and improved adobe walls subjected to monotonic load,it's shown that adobe dimension,improved mud and masonry style have influence on shear behavior of the adobe wall.Meanwhile the mechanical property of the adobe wall such as shear capacity and ductility is presented.Based on the test,the formula of shear capacity for the adobe wall is obtained.
