Behavioral Investigation of Reinforced Concrete T-Beams with Distributed Reinforcement in the Tension Flange

Current design codes and specifications allow for part of the bonded flexure tension reinforcement to be distributed over an effective flange width when the T-beams' flanges are in tension. This study presents an experimental and numerical investigation on the reinforced concrete flanged sectio...
