WebJul 1, 2024 · [Show full abstract] of confining reinforcement, hooked bar spacing, hook bend angle, hook placement, and embedment length. Bar stresses at failure ranged from 22,800 to 144,100 psi (157 and 994 MPa). WebWith a hooked rebar, you need less overall bar length, and less straight development length of bar. I don’t have the ACI equations in front of me, but the straight length for a hooked bar is about half the straight development length. 15. [deleted] • 5 yr. ago. I think my professor told us it is to prevent migration of the rebar through the ...

Equation 1 is still applicable for use in the 2012 IBC but with the increase in F the splice lengths of fully stressed bars will increase by 33%. Significant reductions of splice lengths in low stress areas are achieved, however. The minimums of 12 in. (305 mm) or 40dbwhichever is greater still apply as well. The 2012 IBC … See more Requirements for development length as well as lap, mechanical and welded splices are identical to those for allowable stress design, and … See more The 2012 IBC, by reference to the 2011 MSJC, includes new lap splice criteria where confinement reinforcement is placed.
