25' Beam Span analysis with OWSJ point loads
25' Beam Span analysis with OWSJ point loads
(OP)
I know this is a no-brainer, but I'm having a bit of a brain freeze and don't have access to any books at the moment.
I've got a W12x27 beam, 25 foot span. There is a udl on the OWSJ putting a force of 12.45kips on the beam in three places, 6.25' apart.
I check the Ireq and the beam has lots of capacity to also put a 1kip lifting load (5kips with FS=5)
To also check the Mu for the beam, do I need to sum the moments caused by the three OWSJ loads, then the point load?
Is the length for PL/8 still 25 feet if the OWSJ provide support every 6.25'?
I don't do this every day, and am still just a lowly EIT...
have pity on me. ;)

Speaking of Mu, are you designing the beam in LRFD?
Consult your supervisor for direction if you are not sure. To get the moment diagram, apply point load individually and superimpose each of the moment diagrams (long way), or use the equations in the AISC ASD 9th edition beam equations (better way), or just use a computer program (easy way).
Good luck
