Abstract:
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.
