摘　　要：新型竖缝互锁灌孔复合砌块墙体是一种绿色、环保且低碳的新型砌体结构,为研究其抗压性能与抗震性能,分别对墙体进行轴压试验与拟静力试验,分析灌孔方式与构造柱类型对该墙体抗压承载力、荷载分配与变形协调等方面的影响,以及不同构造柱类型对墙体抗震性能的影响。结果表明,随着现浇构造柱与复合砌体部分强度差的减小,墙体整体变形协调能力有所提升;提出了适用于设置构造柱的新型墙体的抗压承载力计算公式,计算值与试验值吻合度较好;芯柱构造柱对墙体延性的提升效率高于现浇构造柱墙体,而现浇构造柱墙体的抗震承载力、极限位移等指标优于芯柱构造柱墙体。研发绿色、环保、低碳的新型砌体结构是助力国家乡村振兴战略和改善村镇建筑抗灾能力的有效途径,该新型墙体结构为新疆地区村镇建筑提供了一种新的选择。The new type of vertical joint interlocking grouting hole composite block wall is a green,environmentally friendly,and low-carbon new masonry structure.In this paper,we studied the compressive and seismic performance,by testing its axial compression and pseudo-static pressure on walls,respectively.The effects of the grouting hole method and column type on the compressive bearing capacity,load distribution,and deformation coordination of the wall were analyzed,as well as the effects of different column type on the seismic performance of the wall.The results suggest that as the strength difference between cast-in-place structural columns and composite masonry decreases,the overall deformation coordination ability of the wall improves.A formula for calculating the compressive bearing capacity of a new type of wall suitable for setting up structural columns was proposed,and the calculated values are in good agreement with the experimental values.The efficiency of improving the ductility of walls with core column construction columns is higher than that of cast-in-place construction column walls,and the seismic bearing capacity,ultimate displacement,and other indicators of cast-in-place construction column walls are better than those of core column construction column walls.Since developing green,environmentally friendly,and low-carbon new masonry structures is an effective way to assist the national rural revitalization strategy and improve the disaster resistance of rural buildings,this new wall structure prpposed in our study provides a new choice for rural buildings in the Xinjiang region.
