Experimental Study on Influence of Connection Defects on Joint Strength of Half-Grouted Sleeve Splicing of Rebar
| | Type | Specimen’s number | Experimental condition |
| | A | GTZB16-DZ-BM-1/2/3 | The control group of rebar alignment and full grout | | B | GTZB16-DZ-WM-100 mm-1/2/3 | Vertical insufficient grouting height specimen (vertical grouting height is 100 mm) | | C | GTZB16-DZ-WM-20%-1/2/3 | Insufficient compactness specimen (20% of porosity) | | D | GTZB16-PZ-BM-1/2/3 | Rebar offset joint specimen (rebar eccentricity of 5 mm contacts the sleeve wall) | | E | GTZB16-DZ-120/104/88 mm-BM-1/2/3 | Insufficient anchoring length specimen (the rebar insertion depths were 120 mm, 104 mm, and 88 mm) | | F | GTZB16-DZ-BM-30 min-1/2/3 | Grouting specimen after 30 min delay |
