I am about to frame a 28 x36 woodshop. I need an open floor without posts etc. Outside of trusses, what are my other options that are economical and give me an open floor for the shop? Wall heights are 10 feet plus.
A loft area on one end is needed for a temporary bedroom. A loft on the other end would be good for light material storage. thank you. tom

You can't stick frame a roof for anywhere near the cost of tursses. In fact, I'm not sure you can buy the lumber for the cost of trusses.
If you're looking for storage above, attic trusses will do it easily.
Oh sorry, you wanted cheap alternatives to trusses...don't think there are any.
*Tom,I, too am framing a shop right now. Mine's 28' x 40' and i'm using scissors trusses that are bid at about $100 per truss delivered on site with a boom truck. They only drop about four feet at the ridge, so I'm left with plenty of overhead room for a loft or open space. My truss sub assures me that the 28' open span is fine with no second floor joists or cross-shop tie rods. Not only that, he addressed my need to hang a one-ton hoist by sistering up three trusses at the hoist location. Hope this helps.Tom C.
*Tom,Engineered trusses.......no doubt about it.There is no other option for that span that's cost effective in my opinion.Ed.
*Tom, If you want real storage you should explore attic trusses.
*Tom, one other option is to make a hybrid post-and-beam structure, with a king post dropped from the ridge to carry the bottom chord (attic floor), or two queen posts dropped and a collar tie acting as a top chord. These could be spaced apart a good distance with purlins spanning them to carry the roof. You would definately need an engineer to spec how to do it, but if you want to do it yourself and have access to lots of lumber it's possible. Trusses would be much cheaper and easier in most cases, I think.Mike
*Sounds like you just built a truss.
*Ryan, it absolutely is a truss, but I think when most people think truss they think 2x4's and metal splice plates. The suggestion I offered is more of a do-it-yourself prospect (with engineering) and because of the size of the members, you get a lot of usable space between each truss.Mike
*Tom- I just finished a 30' span on a garage addition with attic trusses and an 8 in 12 pitch. Lot's of room for bedroom etc. Don't know how they can sell trusses that cheap.
*Out of curiousity, can anyone give me a hint as to the price difference between wooden trusses and equivalent steel trusses such as they use in commercial and light industrial buildings?
*I stick frame my buildings. For a 26' span, an I-joist, 2 2x rafters, and a couple metal ties run about $50 per truss equivalent.I don't do enginering here so I will not spec te cost of a 28' span. (I would have built the building 26' wide.)
*George, What's the difference between 26 and 28?Jon
