It can actually be relatively difficult to have the PNA in the web of a steel member in composite design since a very large steel section is typically required (and the overall design may not be very efficient). For a W33x221 and a slab thickness of 4-inches (f’c = 4 ksi), please determine the width of the concrete slab (be) that will place the PNA right at the intersection of the bottom of the flange and top of the web. Show all work. Refer to the figure below.
