I stumbled across this forum while searching for some answers to my project. I am a landscape architect and I would like to design a curved pergola as a feature element in my garden design. However, I am uncertain how to build it and write the specs. any ideas would be appreciated.
the beams for the pergola will be 2"x10" stk cedar and support a 2x8 arbor joist spanning 7.5'(the inside width of the pergola beams). The beams will be supported by 10" round fiberglass columns. the inside radius of the pergola beam is 13' with a length of 25' and the outside beam radius is 21' with a length of 32'. so basically i want to take an 7.5' wide pergola and bend it into an arc with an inside radius of 13'. what do you think?
