- Connections at sill plates
- Remember, shear loads are cumulative as they work their way down a building and shear loads are greatest at the base of a building.
- Now we will talk about where bottom plate is sitting on concrete or masonry, call a sill plate
- Sill plate connected with anchor bolts or plates
- Before the load enters the anchor bolt or plate, it must successfully pass through the sill plate.
- Sill plates should be in good condition and free from cracks.
- If a cracked or split sill plate is encountered, it should be replaced before proceeding with the retrofit.
- The figure shows a split sill plate that will need to be replaced before further work can be done. This splitting is a result of earthquake damage.
