Anchor bolts are used to connect structural and non-structural elements to concrete. The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.

This video investigates critical failure modes in concrete anchors. Concrete anchors can fail in a number of ways; during design, engineers have to check all possible failure scenarios and ensure that they will not occur. Watch the video from The Engineering Hub for more info:
The design process involves a number of parameters that need to be carefully considered and optimized. The most important of these parameters include: embedment, bolt diameter, edge distance, and prying.
