Holes on W beam web.
Holes on W beam web.
(OP)
I have a contractor that needs to drill three 1 3/4" diameter holes side by side on a W10x39. What is the rule of thumb or easy way to analzye this? The beam is almost 17foot long with distributed load and 3 point loads. Maybe reinforce the web where the holes are? What is the common way to reinforce the web? Or maybe I wont need to reinforce it.

If still in doubt, check AISC Steel Design Guide #2.

Very good guide to use.
But 1 3/4" holes are pretty small so if you simply space them out a bit it should be no problem.
