针对新疆的村镇居住环境,提出了一种新型复合墙体结构。对带构造柱与不带构造柱共10片新型复合墙体试件进行了竖向抗压性能试验研究。分析了内芯强度、外模强度、高厚比以及构造柱对新型复合墙体结构的破坏特征、轴心受压承载力及变形性能的影响。结果表明,不带构造柱新型复合墙体的轴心受压破坏过程与普通砌体墙体的轴心受压破坏过程相似;内芯强度和外模强度对轴心受压承载力影响较为显著。在上述试验研究基础上,提出了新型复合墙体轴心受压承载力计算公式,轴心受压承载力的计算值与试验值对比表明两者吻合较好。研究成果可为该种复合墙体早日应用到实际工程提供参考。
Aiming at the living environment of villages and towns in Xinjiang, a new composite wall structure is proposed. The vertical compressive properties of 10 new composite wall specimens with or without structural column were tested. The strength of inner core, the strength of outer mold, the ratio of thickness to thickness and the failure characteristics of structural column on the new composite wall structure, the bearing capacity of axial compression and the deformation performance were analyzed. The results show that the axial compressive failure process of the new type composite wall without structural columns is similar to that of ordinary masonry walls. The inner core strength and the strength of the outer form have a significant effect on the axial compressive bearing capacity . Based on the above experimental studies, the formula for calculating the axial compressive bearing capacity of the new composite wall is proposed. Comparing the calculated value with the test value of the axial compressive bearing capacity shows that the two agree well with each other. The research results can provide a reference for early application of the composite wall to practical engineering.
