   got drawings of what you want it to look like?  Usually the structure is burried within and is straight from bearing point to bearing point.

   It depends on a lot of variables, such as load and spans.

   But as a genearl approach, a layout of clamp blocks ( on a floor or such) and laminate layers of plywood or solid stock, but the radius determines what and how you attack this.

   Much more info is needed.

   My diameter is 34 ft. and load will be roof and ceiling  load only with  rafter length of 20 ft. This is designed to be a round portico look on the front of house. Column spacing would be no more than 8 ft. on center.

   FHB within the last 5 years & JLC more recently have had articles on round porch roofs.

   I think the FHB article was the cover story & had a laminated beam.

   It was the Nov '07 issue of JLC.  Cover article.  "Framing a Curved Porch."  By Tim Meehan out of Stove, Vt.

   In the article, the "round" part was a 90 degree turn from the front to the side.

   I think this is the article from FHB I was remembering.

   Found it in the magazine search
