LH joists - end panels

LH joists - end panels

(OP)
Does anyone know why you would select a 5" seat (standard bearing) over a bottom bearing seat (full depth) when using these huge joists?  TIA

RE: LH joists - end panels

pldpe:

1. Cost.  I'm not sure of the exact difference, but I know you pay a premium for non-standard conditions.

2. Depending on what you're bearing on, it's much easier to fill in around a joist seat with (e.g.) masonry than a full depth seat.

3. Possibly lateral bracing of the top flange at ends of the joists over the support.

The only time I've used bottom bearing joists is in cantilever situations.

Easier wall construction?

RE: LH joists - end panels

Lateral stability would be easier to acheive. Also, you wouldn't want your beams set that low unless you had an over;y tall space. Headroom is usually at a premium.
