DG9. Torsion (Beams: AISC 360)
Torsion design is carried out according to AISC design guide 9 (DG9), AISC 360-05 and AISC 360-10 for single span, pin ended steel beams with open and closed section types as follows:
Open sections (I- symmetric rolled)
- A torsion design and an angle rotation check can be carried out for applied torsion forces only
Closed sections (HSS only)
- •An angle of rotation check can be carried out for applied forces only
