The beam shown in cross section in fig. p7.3 is a typical interior member of a continuous building frame, with span 30 ft between support faces. at factored loads, it will carry a uniformly distributed vertical load of 3100 lb/ft, acting simultaneously with a uniformly distributed torsion of 2600 ft-lb/ft. transverse reinforcement for shear and torsion will consist of no. 4 (no. 13) stirrup-ties, as shown, with 1.5 in. clear to all concrete faces. the effective depth to flexural steel is taken equal to 22.5 in, for both negative and positive bending regions. design the transverse reinforcement for shear and torsion, and calculate the longitudinal steel to be added to the flexural requirements to provide for torsion. torsional reinforcement will be provided only in the web, not in the flanges. material strengths are = 4000 psi and f y = 60,000 psi.
