Abstract:
The paper presents a method for determining the resistance of curved reinforced concrete flexuraf members to failure by development of a circumferential "radial tension" crack at the inner tensile reinforcement. Such a failure can be produced by the radial component of the flexural tensile force in the reinforcement. It also covers the design of radial ties that are needed when the radial tension limit of the concrete without ties is exceeded, as well as the design of stirrup ties for combined shear and radial tension.
