Rebar lapping and minimum concrete coverage
A couple quick code questions regarding rebar in the footings.
Does the 40 bar lappong requirement apply to rebar making a 90 degree bend? i.e. would it be ok for two #4 rebars to lap 10 inches on either side of a corner? Or do they need 20″ lapping in a straight plane.
Second question: is the minimum concrete coverage for reinforcing steel in footings 3″ as per the irc? As in 3″+ rebar chairs are required?
