Reinforcement detail: Stress trajectory‐oriented corbel reinforcement

Abstract

AbstractThe article presents a novel design of concrete corbels, where horizontal and vertical stirrups are replaced by main reinforcement bars that are bent down into the corbel web, following the principal stress lines. A test series of three specimen pairs of fanned‐out and conventional reinforcement design, supported by finite element analysis, shows that the same capacity can be achieved with a significantly lower amount of reinforcement steel and a higher ductility.
