Design of Anchor Reinforcement for Seismic Shear Loads

The effectiveness of anchor reinforcement in increasing the resistance of headed studs have been shown by various researchers in the past 15 16 17 Furthermore Sharma et Stirrups as anchor shear reinforcement are proportioned using the anchor steel capacity in shear as specified by ACI 318 14 and the nominal yield strength of reinforcing steel Two stirrups are recommended next to the anchor shaft where the breakout crack in concrete may initiate under a shear force The rest of the required stirrups are placed with a center on
