Column Bears with Custom Standoff
Column bears on custom steel standoff assembly consisting of upper and lower bearing plates separated by a standoff. Upper bearing plate has knife plate or pipe for connection to column. Column is positively connected to knife plate or pipe with dowel-type fasteners. Lower bearing plate is connected to concrete with post-installed anchors. Grout is provided below lower bearing plate for elevation control.
Purpose: Transfer of vertical load from wood column to concrete.
- Capacity of connection is dependent on parallel-to-grain capacity of the column.
- Consider reducing upper bearing plate dimensions relative to column to accommodate potential column shrinkage.
- Standoff allows for architectural finishes and elevates base of column to reduce exposure to potential moisture sources.
