Select a W24 rolled steel shape for the composite section shown below. The beam is simply supported and spaced at 9 feet c/c. The reinforced concrete slab is $41/2$-inch thick. The factored moments are $296\mathrm{ft}.\mathrm{k}$ and $660ft.k$ for the non-composite and composite sections, respectively. The concrete strength is $f_c=4\mathrm{ksi}$, and the steel used is A992. Check the moment strengths for the non-composite and composite sections, and determine the unbraced length of the noncomposite section during construction.
