Scissor Trusses


I am building a standalone garage with a footer base. Garage dimensions are 40 feet wide by 44 feet deep. I plan to use scissor trusses with an 8-12 pitch. Can i still build the walls using 2X4 studs or will I need to use 2X6's? I live in southwestern Pennsylvania. thanks!

Much depends on the wall type (wood, I assume and the stud spacing) and height of the walls. I assume the trusses are designed to fit on a normal wall.

I had scissor trusses made for my 30X56 lake home. The trusses had a 4:12 pitch and interior was about 2:12. I had 9' high 8" concrete block. Because the trusses were so accurate and better than the contractor assumed, he gave me a rebate on setting roofing.

At 40' wide, make sure the trusses do not put in any lateral load into the walls since your snow load can be engineered and the design specified.

thanks for the info. Walls will be wood studs 16" centers. trusses will be spaced 24" center. Walls will be 12 feet high. Will the wall height be an issue?

2x6 would not be that much more and you could get a lot more insulation. what ever you end up doing, i would sheath the walls before you st those trusses to avoid stud deflection
