摘要
选择4个强度等级砂浆,对12个砌体试件进行抗压强度试验,分析其破坏特征及变形等性能。试验表明:内、外叶墙开裂荷载和破坏荷载有一定的变化规律,砌体抗压强度与砌筑砂浆有明显的关系。通过数据分析,提出内外叶墙为不同材质夹芯复合砌体抗压强度建议公式;对2片内外叶墙为不同材质构成的夹芯墙墙片进行抗震试验,根据试验结果,分析该种墙体的破坏特征及其变形性能、强度、延性等抗震性能,试验表明,该墙体的抗震性能良好。
The compression experiments of 12 masonry specimens with 4 different grades of mortar strength were made,it was analyzed its failure behaviors,deformation and other characters.The results show that cracking load and failure load have certain regularities,there is an obvious relationship between the compression strength and mortar.A proposed formula of compression strength is given for the sandwich masonry through data regression analysis.By the experimental investigation of 2 sandwich walls under low cyclic lodging,the failure features and basic seismic behavior such as deformation behavior,strength,ductility relations of this kind of walls have been analyzed.And studies show that this wall’s seismic behavior is excellent.
