Stirrups
Stirrups
(OP)
I'm working on a fairly large concrete wide-module framed building in the US. Falls under the IBC and it's a SDC A structure. For typical interior beams of substantial width, including lateral beams, why would one use stirrups with 90 degree hooks rather than just using stirrups with 135 degree hooks? There will be plenty of spandrel beams where this 135 degree hook ends would be required anyway. So, it just seems keeping one kind is simpler. I'm only talking about the bottom U shaped piece in a two piece stirrup, not the cap piece.

@PUEngineer> In beams of substantial width, normally what maximum lateral distance between the vertical legs you allow?
Not sure, but some codes restrict distance to about 0.75 times effective depth.

@DST: It's a #4 stirrup we're talking about here. I'm trying to keep things consistent in the project. All spandrel beams will have two piece stirrups with the main 'U' bar having 135 degree hook ends. So, it seems simpler to just make that a consistent approach. I usually think about adding legs when the beam width gets over 30".
@msquared: I assume you're talking about the cap in a two piece stirrup. I'm strictly questioning the bottom 'U' piece in a two piece stirrup. Let me know if I'm wrong.
