The Timber Frame Engineering Council (TFEC) formed in 2005 at a Guild conference in recognition of the considerable number of structural engineers among the Guild membership and in response to a felt need for systematic research, discussion and codification of timber frame joinery and structural practices. 
Membership in the TFEC is open to any Guild member with an interest in timber frame engineering. Annual dues are $75 in addition to Guild dues. Join here. TFEC conducts technical symposia at national Guild conferences, publishes bulletins and maintains its own website,
