WebLap lengths for unequal size bars may be based on the smaller bar. The top of sections > 250 mm thick and the top 300 mm of sections deeper than 600 mm are considered to provide poor bond conditions. In these locations, bond strengths are reduced and anchorage and lap lengths are increased accordingly. WebJan 15, 2024 · The project inspector has rejected the laps, saying they must be one square plus 2 inches, or 8 inches total, minimum. The inspector is citing ACI 318-19, section 25.5.4, which covers plain wire WWR tension lap splices for structural slabs. While ACI 318-19 does call for the lap length cited by the inspector, we don’t agree with his interpretation.
