新型多排孔混凝土砌块砌体局部均匀受压分析

Study on new concrete block masonry with multi-row cores on local uniform compression

从研究典型多排孔砌块砌体局部受压承载能力角度出发,结合多排孔砌块墙体中部分孔洞填充保温材料特点开展砌体局部均匀受压能力试验研究。结果分析表明,多排孔砌体局部受压过程中呈脆性破坏特征,力的扩散作用十分显著;通过数据分析拟合确定了该类砌体的局部均匀受压强度提高系数计算公式,并对工程应用措施提出了建议。

From the prospective of the local compression performance of typical block masonry with multi-row cores,in con-sideration of the characteristic that some block cores are filled with insulation material-straw block,the study on the local com-pression bearing capacity of the masonry is carried out. The results show that masonry with multi-row cores fracture in typical brittle manner, and the phenomenon of the stress diffusion is very remarkable. By the data analysis,the formula of added coeffi-cient of strength on local uniform compression is put forward and practical engineering measures are proposed.
