	*Our primary concerns at this moment are how to connect the trusses to the CEB columns. To get a better idea of our model check out the Google Sketchup file in our weblog. Our plan is to pound rebar into the columns and use a large steel washer to cap the trusses on top of the columns. Any solutions and/or thoughts are always appreciated.		*Our primary concerns at this moment are how to connect the trusses to the CEB columns.

New page

[[Image:truss.jpg|600px]]

Truss:
*2x4 lumber (3.5x1.5" in the USA).
*7/16" oriented strand board (OSB) plates
*Plates are 7x16", and the small squares are 7x7" typical
*22 inch high
*Vertical after every 2 diagonals
*Total diagonal length of members from left to righ - 22"
*Verticals are 15" high
*Our trusses are 32 feet long

Learnings:
*If I were to do it again, I would just do the top and bottom parallels, and cover with 24" OSB from 4x8' sheets, on both sides. This is DIY 'engineered lumber'. I call it the wood-OSB sandwich.
*Total cost of truss shown is about $50 for 32' including nails for nail gun
*Total cost for new version is about $40 for the same, and I guess that the strength is much higher for the simple wood-OSB sandwich. Just stagger the joints properly. The weak point in the former is the large number of small pieces. The more monolithic, the better.
