Hopefully this doesn't sound too rude, but if you are building rooms that size you should be hiring a Structural Engineer to do your load calcs. any information on the beam size would be appreciated. The room is 34' x 25'8" and the way it is designed the beam should span the 34'. it seems to me that a single I beam is more cost effective than all this lumber. I have all the formulas for calculating the size of I beam needed but i would like a little reassurance from some other professionals. i have redesigned the lvl support beams as to where it will work but i am increasing the amount of material as to where the cost is getting high. the reason this became an issue is i have another room with a 34' span and a lvl beam will not work because of deflection. instead of using engineered lumber, would it be more cost effective to use a single I beam for the main beam and the tributary. there is also 3 - 24" lvl's that t into this beam about half way that spans 21.5' also supporting joists. in the icc joist table i used live load 20 psf and dead load 10 psf to calculate joist sizes. i have 4 - 24" lvl's to carry the load over the 29' span. To ensure accurate specification and supply, hyJOIST should be noted on plans as HJDepth Flange Breadth hyJOIST e.g.I am designing my house and i have a room that is 29' x 41.5' with 2 different ceiling heights.Please contact Futurebuild LVL for available lengths.* Lengths made to order, lead times apply.
