hook development length
can someone explain to me 12.5.3 length ldh in 12.5.2 shall be permitted to be multiplied by the following factors.....
i feel like i dont really understand 100% for factors a and b.
not almost anymore!
check out our whitepaper library.
a) for all hooks (180 or 90) the side cover must be at least 2.5 incheses.
for 90 hooks, the cover behind the hook must be at least 2.5"
b)is pretty self explanatory.
these are related more for splitting type failures of the concrete as opposed to actual pull-out.
eit, explain behind the hook. meaning the cover to the left of shape l?
not almost anymore!
no, if you follow the bar from the middle of the
ok, so if this hook is for the dowel at the base of a retaining wall going into the toe, then the minimum concrete cover is 3" because it is againts the earth (no form). does this mean i can multiply this factor?
not almost anymore!
yes
