TFEC Practice Bulletins

These Practice Notes have been developed by the Timber Frame Engineering Council as a source of advice to structural engineers on practice-related issues, where often there is little other advice available. The notes are intended to inform TFEC Members about issues that may affect them in various ways and in various capacities.

TFEC Technical Bulletins

The Technical Bulletins of the Timber Frame Engineering Council provide guidance concerning the building performance standards of the TFEC. These bulletins are intended for use primarily by structural engineers, design professionals, and builders for interpreting and understanding issues in the timber frame engineering process as well as other pertinent information relating to the design of timber frame structures.

TFEC 1 - Standard for Design of Timber Frame Structures

The Timber Frame Engineering Council developed this Standard to define the engineering and design requirements for timber frame construction. A timber frame shall be regarded as a structural building frame system or a portion thereof that is composed of heavy timber members in which connections between interlocking members are created by carpenter-style joinery using wood pegs and wood wedges.

This Standard is not intended to preclude use of other materials, assemblies, structures or designs not meeting the criteria herein, provided it is demonstrated by analysis based on recognized theory, full scale or prototype loading tests, studies of model analogues or extensive experience in use that the material, assembly, structure or design will perform satisfactorily in its intended end use.

This Standard is intended as a supplement to provisions of the National Design Specification for Wood Construction (ANSI/AF&PA NDS©, Reference 1). In the event of conflicts or contradictory requirements between this Standard and the NDS©, the provisions of the latter specification shall apply.
