Abstract
A theory for the design of reinforced concrete
short cantilever under pure torsion is presented. It is
based on the shear-friction theory. The failure plane
assumed is supported by observations on test-specimens.
Based on the failure surface, the failure torque was
found to be primarily a function of percentage of
longitudinal reinforcement, dimension of the cross
section and the characteristic strength of steel.
The torsional capacities of reinforced specimens tested
agreed well with the theoretically predicted values.
Torsional reinforcement perpendicular to the assumed
crack at the root of the cantilever is preferred to
reinforcement inclined at 45 to the axis of the short
cantilever.
