Concrete Breakout<br />
Failure of anchors in concrete relies on 6 factors:<br />
• Compressive strength of the surrounding concrete.<br />
• Strength of the anchor.<br />
• The anchors’ embedment depth h, This is defined by the anchor length and the set-down.<br />
• The anchors’ distance from any edge or face E. To fully develop the concrete breakout cone, E needs to<br />
be equal or greater than the designed minimum edge distance shown in Table 1 (Below).<br />
• The distance between anchors c. To fully develop the concrete breakout cone, c needs to be equal or<br />
greater than 3 x the designed minimum edge distance. (See Table 1 Below).<br />
• Direction of loading.<br />
• Concrete breakout will occur at a proportionally reduced capacity when anchors are closer to edges or<br />
faces than the designed minimum edge distance shown in Table 1 (Below) or with a distance of less than 3<br />
x the designed minimum edge distance (See Table 1 Below) between anchors.<br />
