what is deflection of composite decking

composite construction composite slabs. slabs are formed from steel decking and a concrete topping. during concreting, the deck supports the weight of the wet concrete; in service . additional reinforcement. composite beams. composite action increases the load carrying capacity and stiffness (i.e. reduces the deflections) by factors of around 2.
