Analytical Study on the Bending Behavior of the Composite Beam with T-shaped Shear Connector Under Partial Interaction

This paper presents a comprehensive study on the bending behavior of composite beams with T-shaped shear connectors under partial interaction. Numerical analyses were conducted to investigate the effects of various parameters, including stud spacing, stud diameter, concrete strength, and beam depth, on the behavior of composite beams. The findings showed that the behavior of these beams is highly dependent on the interaction between the steel and concrete, and the shear connectors play a critical role in ensuring the composite action. The study also highlighted the importance of using partial interaction in the design of composite beams, as it can lead to a better match of applied and opposing moments and provide some economy in the arrangement of connectors. The analytical results obtained shows that the C1 beam can carry maximum amount of load. The beam D1 with full interaction carries 9% lesser load as compared to C1 beam. The A1 beam and C1 beam almost shows similar behavior. Based upon analytical results the C1 beam, i.e., five connectors with 250 mm center to center spacing carry the maximum number of load.
