Transformed Section of LVL and Wood Joists
Transformed Section of LVL and Wood Joists
(OP)
I want to sister an LVL to an existing wood joist. Anyone ever calculate transformed section properties? Do you think using the same method as a flitch beam is acceptable?
Any general thoughts on finding transformed sections?

And just so I can sleep tonight - what is a flitch beam?
(Most of my experience has involved bridge structures, and sometime the terminology from other areas is new to me. I assume that this is a carpentry term?)
Sorry about the responding to a question with a question business, but I was curious on both points (transformed section and flitch beam).
Thanks

HBA has a flitch desing guide see:

I designed a flitched beam (just learned to word and I'm already throwing it around like I'm the king of flitched beams!) once for a friend of the boss (no, not my wife, the company president). The timber contribution was so insignificant, that I just ignored it. Of course, in that case, I added two steel plates to a timber beam, rather than one steel plate sandwiched between two pieces of lumber. But still, 96 pages?!!
All kidding aside, thanks for the post. I downloaded the guide and will keep it for future use.

As for sistering an LVL to an existing solid sawn, I was hoping for a conservative shortcut, instead of relative stiffness of each piece.
