The multiple layers shall be fastened together to form asingle cage. If the multiple layers of a cage conta

Requirements for placement and protec-tive covering of the concrete from the inner or outer surface ofthe pipe d

43、um specified tensile strength of the steel. For butt-welded splices in bars or wire, permitted only with helicallywound cages, pull tests of representative specimens shalldevelop at least 75 % of the minimum specified tensile strengthof the steel.10.4 Lapped Splices of Circumferential Reinforcement:

Splices of larger than #6 bars shallmeet the requirements of ACI 318.10.4.2 If la
45、pped splices of circumferentials consisting ofwelded smooth wire reinforcement or welded deformed wirereinforcement are not welded, the overlap measured betweenthe outermost longitudinals on each side of the splice shall beno less than the spacing of the longitudinals plus 1 in. or Ld,where:Ld5 0.27
46、Awrfys =f c(3)whichever is greater.10.4.3 At the option of the manufacturer, a more detailedanalysis may be made and the following exception to therequirements of 10.4.2 may be applied. If the area of circum-ferential reinforcement is at least twice that required forflexure, the first requirement of
47、 10.4.2 shall not apply. Theoverlap measured between the outermost longitudinals on eachside of the splice shall be no less than that required by Eq 3,or1 in., whichever is greater.10.4.4 Alternative splice designs that differ from 10.4 maybe submitted to the owner for approval.10.5 Development of Q
