Web4.1.7 Requirements for Static Concrete Pryout Strength in Shear , V. cp . or . V. cpg: The nominal static concrete pryout strength of a single anchor or group of anchors in shear, V. cp. or V. cpg, must be calculated in accordance with ACI 318-14 17.5.3 or ACI 318 -11 D.6.3, as applicable, using the value of k. cp. described in Table 3, and the ... WebJun 28, 2024 · Anchor bolt pryout will only control for very small embedment lengths. Masonry crushing is usually the failure mode that controls the design capacity. The masonry code has always had the requirement that there be at least 1/4-inch clearance between the anchor bolt and masonry unit for fine grout, and 1/2-inch clearance between the anchor …
