摘　　要：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 Xinjiang village living environment,a new type of composite wall structure was proposed. The compressive properties of a total of ten new composite wall specimens with and without constructional columns were tested under the actions of vertical loads. The influences of inner core strength,outer mold strength,high-thickness ratio and constructional column on the destructive characteristics,the axial compression bearing capacity and deformation properties of the new composite wall structure were analyzed. The results show that the axial compression destructive process of the new composite wall without constructional columns is similar to that for the ordinary masonry wall. And the influences of inner core strength and outer mold strength are obviously on axial compression bearing capacity. On the basis of the above experiment study,the calculation formulas of the bearing capacity for the new composite wall under axial compression were put forward. The comparison of the calculated values with the experimental values of the axial bearing capacity shows that the calculated values coincide well with the experimental values. The research achievements can provide reference for the application of this kind of composite wall in practical engineerings as soon as possible.
