Concrete cone failure of single cast-in anchors under tensile loading – A literature review

Extended concrete capacity design method for anchors close to non‐rectangular edges

“…The RHT model assumes that damage accumulates due to inelastic deviatoric strain, which can result in strain softening and reduction in shear stiffness. A broader overview of the tensile behavior of anchors can be found in the review articles [31][32][33] and in the technical volumes. 21,34 The cone breakout failure is assumed to initiate at the lower end of the anchor and propagate to the surface at an angle of 30 to 40 to the horizontal plane.…”

An experimental study of the bond behavior of twisted steel bars embedded in mortar cylinders and in the joints of masonry wallettes

“…PVC tubes were used as molds (Figure 4a). A length of 50 mm from the top of the cylinder was left unbonded, such that during the pull-out, failure was given to the bar pull-out and not to an incorrect tensile failure of the mortar cylinder [33,34]. Plastic pipes were used to create the bond break (Figure 4b) and in order to avoid the formation of voids, the compaction of the fresh mortar was carried out manually with a rod (Figure 4c).…”

A parametric finite element study of concrete cone failure in headed bars under tensile loading

“…When subjected to tensile loading, it exhibits the following failure modes: steel failure, pullout failure, side-face blowout, concrete splitting failure, and concrete cone failure (Hayek 2023) (Figure 1). The specific failure mode depends on parameters such as concrete compressive strength, embedment depths, steel strength, edge distance, spacing between headed bars, and other variables, as discussed in detail by Karmokar et al (2021). In recent decades, the successful use of a headed bar as a replacement for the traditional method has been demonstrated in experimental research studies by DeVries (1996), Thompson et al (2005), Ghimire et al (2019), Ferreira et al (2021), and Santana et al (2022).…”
