The use of steel deck-plate has continuously increased in slab construction because of efficiency of construction-ability. Slab member is not only resisting the loads but sensitive the deflection. Generally, steel deck-plate slab has higher equivalent moment of inertia than normal RC slab because of its bottom steel plate. In this study, stiffness variation of the various slab was experimentally examined.
