Below are some progress photos depicting substructure reinforcement and temporary bearing beams for our project replacing a center truss girder on an early 19th century post and beam house in Harrison: NY.
Cracked main girder in post and beam ceiling in 18th or early early Nineteeth century farmhouse Harrison NY
The house has been heavily modified over the years and it appears that in a circa 1980s renovation a load bearing central truss was cut out leaving only a single undersized beam to bear floor wall and roof loads on an approximately 30′ x 17′. The old hardwood beam cracked under the load and is being replaced by a new solid white oak beam with a pair of steel angles inserted from the top for reinforcement.
I will publish details of this as the work proceeds.
Temporary load bearing beams support floor before removal of cracked center girder. It is my supposition that the rod seen in the first photo attached to a structural truss. Sloppy renovators in the 1980’s modified the roof line and seem to have cut out the upper section of the truss and rod leaving this beam alone to carry much of the second floor of the house.
