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。
Select four strength grade mortar, 12 masonry specimens compressive strength test, analysis of its damage characteristics and deformation properties. The tests show that the cracking load and failure load of the inner and outer leaf walls have some changes, and the compressive strength of the masonry has obvious relationship with the mortar. According to the data analysis, the proposed formula is proposed for the compressive strength of sandwich composite masonry with different materials. The inner wall and the outer wall are made of different materials, and the seismic tests are carried out. According to the test results, The failure characteristics of the body and its deformation performance, strength, ductility and other seismic performance, tests show that the wall of a good seismic performance.
