Torsional analysis
Torsional analysis
(OP)
A w8x40 steel beam with a continuous 3/8" x 14" wide steel plate welded to the top flange, spanning 25.33', fixed at both ends into a masonry wall, with precast concrete roof planks bearing 8" from the beam center onto the steel top plate with a unifrom total dead and live load producing 920 PLF. Can this beam resist the torsion created by this eccentric load? What formula is needed to check this condition?

The greater the torsion the greater the fixity required at the masonry wall. The beam-to-wall connection will need a good look.
