Many engineers feel uncomfortable that they must currently rely on percent-of-composite-action values obtained from a connector manufacturer to achieve full or partial-composite action in prestressed concrete sandwich wall panels. Engineers are dependent upon these recommendations to establish their designs. This project tested six full-scale concrete sandwich wall panels to evaluate the percent composite action of various connectors. These resulting values were then compared to those provided by the composite connector manufacturers. This study concluded that the reported degrees of composite action from each manufacturer are considered conservative in all instances for the connectors tested in this study. Additionally, the intensity and type of connectors are important factors to be considered in determining the degree of partial composite action in a panel.
