The steel grid composite deck is a composite structure made of a concrete slab disposed over a steel grid. In this study, the punching shear strength obtained experimentally and the shear strength calculated by design equations of ACI 318 and Eurocode 2 are compared. The result shows that the experimental strength is best estimated by the design equation of Eurocode 2 which considers reinforcement ratio.
