This paper presents the design of a cantilever canopy and its supporting beam for a sport stadium. The reinforced concrete beam is analyzed and designed under the effects of shear load, bending moment, and torsion. The design was carried out following the American Concrete Institute’s most recent standard (ACI 318-19). When there is torsion on reinforced concrete sections, the design steps become more complicated. The formula to design and the minimum requirements for both the longitudinal and transverse bars are changed since the torsion is included. The design of flexural longitudinal bars is not affected from torsion however, there are needed more longitudinal bars against torsion which affect the spacing and the detailing of longitudinal bars. For transverse bars, when the torsion is considered, the stirrups are designed as the sum of transverse and shear requirement. The main focus of the paper is to show the design steps and detailing of structural concrete elements under the effect of torsional moment.
