Spliced continous wood beam
Spliced continous wood beam
(OP)
Just wondering, when designing a continous wood beam (in this case 3 ply 2x10) how do you consider the inevitable splice? I have been told different ways. One way I've been told was to analyze this as a 2 ply beam without splices even though it will be 3 plies. Another way was to limit the splices or supports.
I check my references books and none address this.
Any help would be appreciated

RE: Spliced continous wood beam
You probably could assume 3 ply for deflection, but shear and bending only 2 ply for sure. So why bother?
RE: Spliced continous wood beam
Having said that, I have in the past specified splice locations and neglected the ply that has the splice in it (as you have noted). I think in the condition I was working with, the two-ply continuous beam had less deflection than the three-ply simple span.
