A simply supported inverted T-beam has a clear span ln = 32 ft
and is subjected to its own weight and the point loads P as shown.
The point load P consists of a service dead load of 16 kips and a
service live load of 28kips. Design #3 vertical stirrups for the
beam (ignore any torsional effects). Assume d = 41.5 in., ƒc’ =
4,000 psi, and ƒy = 60,000 psi.
