WebPryout Failure — Pryout failure occurs for shallowly embedded anchors when a base material failure surface is pried out "behind" the anchor, ... to apply the appropriate load adjustment factor to either the allowable tension based on bond strength or allowable shear based on concrete edge distance for a given base material temperature. While ... Webyields before the concrete crus hes. In the design of an embed-ment for direct loading, the philosophy leads to the require-ment that the concrete breakout, concrete pullout, side-face blowout, and pryout strength must be greater than the tensile or shear strength of the steel portion of the embedment. ec 始まりWebEssentially, when using Appendix D provisions, the bars are designed in the same manner as anchor bolts. This concept assumes the “anchorage” is subject to three possible failure modes in tension: steel failure, concrete breakout and bond failure; and three possible failure modes in shear: steel failure, concrete breakout and concrete pryout. ec守口八雲センター
