Experimental and numerical assessment of the location-based impact of grouting defects on the tensile performance of the fully grouted sleeve connection by Kulondwa Kahama Espoir, Xie Fuzhe, Chunhua Lu, Isaac Offei

“…Corresponding numerical models were proposed, validated and used to conduct a sensitivity analysis of the connection to the defect's location while considering different design confinements of grouting materials. Experimental and numerical studies revealed the following outcome: In consideration of confinement parameters, when the defect of size 3d is located in the mid-span anchorage length, the variation of the sleeve-to-bar diameter (ds/d) from 2.66 (lower design limit) to 3.55 (upper design limit) changed the drop in the ultimate capacity from 19% to 44% below the connection's design requirement. …”
