WebAccording to IS 456: 2000. For flexural tension, the lap length shall be Ld that is development length, or 30d whichever is greater is considered. Where d is the diameter of the bar. Generally, the development length is 41d where d is the diameter of the bar. For direct tension, the lap length should be 2 Ld or 30d whichever is greater is ... WebNov 2, 2008 · Hooks can't develop in compression - what you do is count on the vertical dowel length exclusive of the hook to see if you have enough length. The minimum compression length for any bar is 8" and this raises the question as to how you could ever use a 10" thick footing and develop the bar with 3" bottom cover.
