| Abstract |
Previously study, An exact solution based on the stiffness of shear connectors was developed which is not dependent on the load cases. The equivalent rigidity of composite beams considering three different loading types was first derived based on equilibrium and curvature compatibility, from which a general formula to account for slip effects was developed. To validate this approach, the predicted maximum deflection using the proposed method is compared against currently used equations for the calculation of the beam effective stiffness. For typical beams used in practice, shear slip effects may results in stiffness reduction up to 18% for short span beams. For full composite sections, the effective stiffness with the AISC specifications are larger than that of present study, meaning that the specifications are not on the conservation side. For partial composite sections, the AICS predictions are more conservative than the present study. |
