Behavior and modeling of reinforced composite slab in tension

The load-deformation behavior of a reinforced composite slab is required to determine the moment-rotation behavior of a composite partially restrained connection. A component model that can be used to predict this load-deformation behavior is developed in this paper. The model is validated by comparing it to the results of four full-scale experimental tests that were designed to isolate the load-deformation behavior of the composite slab. Behavior models for reinforcing steel, concrete tension stiffening, and shear studs are presented or developed to provide the necessary tools to predict the composite slab load-deformation behavior.
