The embedment requirements for anchorage steel are not clearly defined by most codes and are left largely to the discretion of the design engineer Also there are no provisions to prevent a brittle failure in the concrete as opposed to a ductile failure in the anchor bolt as provided for with a probability based limit states design or Load and Resistance Factor Design LRFD for
