I would like to design and possibly build an octagonal timberframe with no central post. The diameter of the building would be approximately 66'. Is this possible or am I nuts? The bents would form 2 concentric rings 12 or 14' apart supporting the rafters. The rafters would rise at an 8/12 pitch and be approx. 28' in length from the inner concentric ring. I hope this makes some sense. If not, please forgive me.
Thanks, Steven.
