I NTRODUCTION

teel anchors are an essential design component for fastening structural items to (reinforced) concrete or masonry. Anchors are used to attach steel elements to supporting concrete members. They are often overlooked and assumed to be a secondary design element. Nevertheless, they transfer external loading to the concrete structure and they are therefore very important and need to be designed correctly. There exist two basic kinds of anchors: post-installed and cast in. Cast-in anchors are bolts that are installed in the concrete before it has set and dried. Post-installed anchor bolts are installed after the concrete is set in place and completely dried. Anchor-concrete fastening systems fail mostly through concrete-related failures. According to the type of loading (tension/shear) which is applied to the system, several kinds of failure can be distinguished: pull-out failure, steel failure, side-face blowout, concrete cone breakout and concrete splitting for anchors subjected to tensile loading or concrete pry-out failure, concrete edge failure and steel failure for anchors S
