Concrete cone is one of the failure modes of anchors in concrete, loaded by a tensile force. The failure is governed by crack growth in concrete, which forms a typical cone shape having the anchor's axis as revolution axis. See more ACI 349-85 Under tension loading, the concrete cone failure surface has 45° inclination. A constant distribution of tensile stresses is then assumed. The concrete cone failure load See more • Fracture mechanics • Concrete fracture analysis • Size effect • Anchor Cone See more WebThese anchors are used with a hanger bar, also known as a tension bar, where the concrete is too weak for a cone anchor. They are ideal for thin panels and other applications where the concrete shear cone developed by the anchor is insufficient to provide the working load limit of the anchor e.g. low strength concrete.
