beam bar splice bend
beam bar splice bend
(OP)
In lap splice in beam bars. Won't bending of grade 60 bars to align the splice bars cause some slight brittleness in the bend corner of the splice? Is no bending recommended at the cost of some looseness in the surrounding stirrups?

This is an example of a beam top bar midspan splice.....
bar 2 ********************* **************************** bar 1

bent bars
the bar 2 is bent so that the ends can be bundled with the upper bars. Bending is done so that all stirrups can be aligned with all the bars in the beam. But for grade 60 bars, is it better not to bend it?
RE: beam bar splice bend
Just imagine a top bar midspan splice, you have to slightly bend the bar in one of them to be bundled with the other bar. Has anyone done any grade 60 splice without bending?

BAretired. You mean you bend one of the bars in the splice? Are you not concerned that grade 60 bars are more brittle hence bending can cause some loss of strengh?
RE: beam bar splice bend
Using straight lap bars is possible, but the lap bars cannot be "wet set" in the lower column or strength will be lost. Offsetting the upper bar relative to the lower bar is sometimes done but this is not possible for smaller columns. Running vertical bars two tiers instead of one results in more bars than required at the splice, so some loss of strength can be tolerated. It also results in fewer splices.

BAretired. I'm talking about beams. Have you done any splicing without bending in the beams?
