TexasRedNeck:
Is there a real man here that has access to engineering software that can help me with deflection calculations for a timber beam?

It’s been 30 years since I had to use calculus and I really don’t want to spend 2 days fumbling through a calculation trying to reeducate myself.

I can provide the load, span and modulus of elasticity and beam cross section if someone has access to software.

What I am attempting to do is design a simple outdoor structure to support a roof for an outdoor kitchen.  The main calculation will be for a simple span of 24 feet with evenly distributed load using a single southern pine timber beam.  Just trying to figure out if a 6x12 will work or if I have to go deeper to a 14.  Or if its not possible do I have to break the span to 2 12 ft spans

Thank you gentlemen

I have access to the software.  Not sure if I would have the correct properties for pine.  Wood is very hard to get an accurate calculation like this done on.  The strength properties of wood will vary not only by the species but also the conditions it was grown in, location of knots, how it was dried etc...  24' sounds very long for an unsupported span though.  12' seems doable.  Maybe before spending to much time doing the calcs bounce it off BigDave.

Charles I am pretty positive that will meet your requirements but I’ll send the question to our structural engineer who does our homes today.  See what he kicks back,

Generally speaking a beam can go 1.5 it’s thickness.  In feet.   2x8 can span 12 feet and so forth.

Are you using a pine beam instead of a gluelam or orther beam for some reason?

Charles, most real lumber yards can access this info for you. And yes why not laminated beam?
