Determine the following given the design data:$*$ select structural member cross$-$section, materials and loads$*$ perform design following the allowable stress criteria $($feasibility domain$/$steel envelopes$)*$ determine tendon profile $($variation of eccentricity along the span of the beam$)$ and number of strands $($i$.$e$.,$ area of reinforcement$)*$ verify the behavior of the section at ultimate $($flexure and shear$)*$ verify the deformations $($serviceability limit states$)$
