TIMBER FRAME ENGINEERING

115 year old timber frame barn frame gets new pegs and mortise and tenon repair

FEA of Timber Frame under high load shows stress at base of posts

New foundation with flexible post mounts solve stress problem identified in FEA study

Octagonal Pole Frame for large commons house with straw bale roof and 15’ tall straw bale walls. The building also received the first known Code approval for an earthen floor system. Several similar designs have been based upon this particular framing system.

Although we do not advocate the use of straw bales as a building or insulating material, we have nevertheless on many occasions provided engineering services for such structures.

The FEA of the above pole framing system is shown here. Notice that as in many framed structures the stress is maximum at the foundation attachment.

   Engineered Tree House construction is not
   something many plans examiners have reviewed
   before. Differential lateral movement
   amongst supports must be provided by
   slider plates, rocker arms, flexible linkages,
   hanging cables and the deflection of connecting
   members themselves. Lateral rigidity
   in the support frame must be provided
   along with simultaneous controlled vertical
   flexibility. Greenwood Engineering has pioneered
   the design and manufacture of special
   high strength live tree fasteners, along
   with related hardware systems.
