Abstract
In order for dissimilar materials to act in a composite manner, forces must be transferred between the materials so that they achieve a state of internal equilibrium with one another. Previous editions of the American Institute of Steel Construction (AISC) Specification briefly address load transfer; however, these provisions are quite limited in scope and clarity. The 2010 AISC Specification significantly expands load transfer requirements in a new section. Clear guidance is now provided for the allocation of forces between steel and concrete sections as well as for force transfer mechanisms used for composite members. This paper reviews the new AISC provisions, discusses their application, and provides a brief technical background to the new headed stud anchor provisions as they relate to load transfer.
