What 29 CFR 1926.756 requires (plain English)
29 CFR 1926.756 governs the placement of beams and columns during steel erection: the moment when structural members are set and connected as the frame rises. It is part of Subpart R (Steel Erection).
Its central rule is a connection minimum before the crane releases the load: during the final placing of solid web structural members, the load must not be released from the hoisting line until the member is secured with at least two bolts per connection, of the same size and strength as shown in the erection drawings, drawn up wrench-tight (or the equivalent as specified by the project structural engineer of record). For columns, the standard requires a minimum of four anchor rods (anchor bolts), and columns must be evaluated for stability. Diagonal bracing and other stability requirements apply where needed.
These requirements address a specific, deadly failure mode: a member that is released from the crane before it is adequately connected can rotate, slip out, or fall, and columns on too few anchor rods can topple. By fixing a minimum connection (two bolts) and a minimum column anchorage (four rods) before the load is released, 1926.756 keeps each piece of the frame secured as it is added, preventing the dropped-steel and partial-collapse incidents that have killed ironworkers.
