Traditional timber framing was developed over centuries by trial and error while combining art and science. Modern designs and an intrinsic need to validate traditional timber framing has led to an architectural and engineering scrutiny of materials and methods not prescribed in codes and standards. Proprietary fasteners and steel hardware have become commonplace for non-traditional and hybrid timber framing. Traditional timber framing does not employ these materials as primary mechanisms. On-wood, in-wood, to-wood connections are the essence of traditional timber framing. Part 1 will begin with general design criteria and standards. The discussion will include what traditional timber framing is and what it is not, effects of seasoning checks and moisture content, and guidelines for effective timber framing design.
