RE: Residential construction-hip beams

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Domenic,

The ridge board only serve as a bearing if you have ceiling joist that will
take care of the tension at the bottom of the rafter or else the ridge board
should act as a beam.  If you have a ceiling joist, make sure it is designed
for the amount of tension cause by sloping rafter, if not then the ridge
board should act as a beam.  The same thing with hip beam. If you cut a
section through the hip beams, you can see truss type configuration with top
(rafter) and bottom (ceiling joist) members but with no web members. If you
don't provide web members, then you have to design the hip beam as a beam.
If you provide web members, the  hip beam will act similar to ridge board,
i.e., will serve only as bearing to transfer axial forces at the joint.

Hope this will help.

I would like to know how engineers address hip beams in residential
construction. Are they carrying members or similar in nature to ridge
boards?
I am of the opinion that they are non-structural and do not require to be
designed.

Any feedback would be appreciated.

Thanks,
