What is the primary purpose of anchor bolts in masonry?

The primary purpose of anchor bolts in masonry is to bolt the sill plate to the concrete masonry unit (CMU) foundation. This connection is crucial as it provides stability to the structure by anchoring the wooden framing of the building to the foundation. Anchor bolts help resist lateral forces, such as those from wind or seismic activity, ensuring that the structure remains anchored and does not shift or move.

Without properly installed anchor bolts, the integrity of the connection between the sill plate and the foundation could be compromised, leading to potential structural failure. This makes anchor bolts essential in the overall design and safety of masonry constructions.
