Aisi E 1- Volume Ii- Part Vii Anchor Bolt Chairs

From a code-enforcement perspective, Part VII is invaluable. Building officials now have a benchmark. A shop drawing showing an anchor bolt chair must be accompanied by calculations referencing Part VII, ensuring that the chair will not fail prior to the bolt yielding. This elevates the chair from a detailer’s afterthought to a verified structural component.

For the designer, Part VII offers a flowchart-like procedure that eliminates guesswork. For a given anchor bolt size (e.g., 5/8-in. diameter), the engineer can select a standard chair angle (e.g., L3x3x1/4) and quickly verify the three modes using provided equations. The standard also imposes minimum edge distances and weld sizes, which effectively outlaw unsafe “homemade” chairs with undersized angles or intermittent welds. aisi e 1- volume ii- part vii anchor bolt chairs
