WebASCE 2010 Structural Congress - Concrete Breakout Strength in Tension for Vertical Vessel Anchorage in Octagon Pedestals The design of circular pattern anchor bolt group is simplified as design of a single anchor bolt with 3 side free edges sawcut at midway between adjacent anchors. The simplified design method uses the following assumptions WebOverturning tension anchorage forces at the ends of shear walls in these projects can routinely be in the 40 kip range and even get as high as 60 kips or more. A 1” diameter high-strength anchor in the middle of a 12” thick, 5,000 psi uncracked concrete slab will achieve roughly 35 kips in tension at allowable stress design (ASD) levels for ...
