PD35 k PL60 k. Wood Post Knife Plate Design. The Knife Plate Connection consists of a vertical plate welded to the column cap plate.

2 Determine yield mode capacity at each bolt shear plane. Knife plates are a category of connection hardware pieces that collectively act as a bridge to transfer the forces from external structures to the structure of the building through the siding and waterproofing. From exposed powder-coated steel plates to hidden galvanized knife-plates FraserWood will utilize our 3D model to ensure the connections are fabricated.

They are designed to have a minimal horizontal presence and to be as easy to waterproof as possible. Figure 2 b shows a design that was considered. I do as Mike describes.

The following guidance is intended to provide for life safety and thus the resistance of the connection is required to be checked at maximum loads only. Break out the pen and paper and figure out a suitable stiffener shape and weld those stiffeners to the knife plate. The maximum loads are the loadings specified in AASHTO Article 1047.
