Select a composite floor deck that spans $2100mm$ with a slab thickness of $100mm$ and a deck thickness of $0\mathrm{.}91mm.$ The deck carries a dead load of $2$kPa and live load of $4\mathrm{.}8$kPa. The total load deflection is $\frac{L}{360}.$ Select a suitable single span composite deck. $(15q,$ minutes$)DL=2$RPa,$LL=4\mathrm{.}8$RPa,$\frac{2100(mm)}{360}=\frac{5\mathrm{.}8}{b}ar(3)$ Type $20$
