Experimental Study on Compressive and Seismic Performance of New Type of Vertical Joint Interlocking Grouting Composite Block Wall
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 capa-city,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 com-posite 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 indicat-ors 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.
