1- Explain the rationale behind using T-beams in concrete floors construction, compared to other options, such
as one-way or two-way slab. Do you think T-beams offer any economic advantage over one-way slabs?
2- Calculate the moment capacity (practical moment) for a T-beam with b=36 in, bw=12 in., hf=4 in and d=22
in. Use f’c=4,000 psi and fy=60,000 psi. The reinforcement is four No. 8 bars.
