Anchor bolts connecting steel framed walls to foundations must extend at least how many inches into concrete?

The standard requirement for anchor bolts connecting steel framed walls to foundations is that they must extend a minimum of 7 inches into the concrete. This is important for ensuring the structural integrity and stability of the connection between the steel frame and the foundation. A depth of 7 inches helps to sufficiently embed the bolt within the concrete, allowing for adequate load transfer and resistance against shear and pulling forces that may occur during the building's use or in adverse conditions, such as earthquakes or high winds.

Using anchor bolts of the appropriate length is crucial in construction to provide the necessary anchorage that can sustain the weight and structural demands placed on the steel framework. The 7-inch minimum ensures that the bond between the bolt and the concrete is strong enough to prevent pull-out and other failure modes that could compromise the overall safety of the structure.
