Abstract
Brackets and corbels are increasingly used to transfer
loads to beam and wall elements. Where corbels are
located along the bottom of spandrel beams or just
above wall openings, hanger reinforcement is needed
to transfer the applied load to the upper region of the
member. This paper reviews past practices and proposes revised equations for the design of corbel hanger
reinforcement. The recommended procedure accounts
for the eccentricity of the applied load as well as shear
and torsion carried by the member below the applied
load. Unlike past practices, accounting for eccentricity
of the applied load will avoid hanger reinforcement
deficiencies that could require retrofit or cause structural failure.
