    The document provides information on the design of a reinforced concrete beam including dimensions, material properties, and calculations of reinforcement ratio, factored load capacity with and without fibers, and stress on reinforcement. It also provides dimensions, material properties and calculations for the design of a headed anchor embedded in concrete including concrete cone capacity, steel plate capacity, shear capacity, and threaded rod capacity. Further, it summarizes the design capacity calculations for post-installed anchors in cracked concrete considering concrete cone failure, pull-out failure, concrete splitting failure, and steel failure.
