What are your conditions?
Do you have a sketch or pictures that can provide a visual aid to your description?
Is the 16' span the gable end of the gable portion of the roof?
Ok. Now that I have a good understanding of what you're looking for...it is typically one question per thread. I can answer two with this one, but the tie question should be asked separately. It's quite a bit more involved. Is that reasonable?
I can submit an additional service offer for you to consider to do it all here.
It will just be member sizes and checks, though, not connections. Unless you prefer to have the connections designed and detailed, too. Just let me know since it will affect the offer.
I will submit the offer for member designs without connection designs
That was why I initially said that. Spacing out the ties makes the analysis of the eave beam more complex. I will assume load is vertical only.
What is the city and state so I can look at snow loading?
A 7" x 16" 2.0E LVL will work for strength and limit total load deflection to about 3/8"
The size is not controlled by strength, it's controlled by deflection.
Deflection is how much the beam sags. I did consider vertical load only, but I still have to check the vertical deflection for that vertical load.
You can use a 5.25" x 14" 2.0E LVL if you're ok with a little over 3/4" deflection under a full design load.
Hello. Do you have any other questions for me on this topic? If you could rate my answer, I would appreciate it.
