10.7.5 Splices of Longitudinal Reinforcement
(a) For tied columns, where ties throughout the lap splice length have an effective area not less than 0.0015hs in both directions, lap splice length shall be permitted to be multiplied by 0.83. Tie legs perpendicular to dimension h shall be considered in calculating effective area.

|Tensile bar stress||Splice details||Splice type|
|≤ 0.5fy||≤ 50% bars spliced at any section and lap splices on adjacent bars staggered by at least ℓd||Class A|
|> 0.5fy||All cases||Class B|
