Description
Sheng Gu, Jun Yang, Saifeng Shen, and Xing Li test a repair for a building joint in 2024. Prefab concrete parts join through grouted sleeves, but missing starter bars in the joint layer can cripple the link. The flaw shows up after quality checks or build errors.
The team proposed a fix and built forty-five test pieces with varied settings, plus nine pieces to check weld fit. Two sleeve steels welded well to the bars; cast iron did not. With a long enough weld, pieces failed by bar snapping rather than joint slip. The fix looks workable for the defect, they conclude.
