THE BASICS · DAY 003 / LESSON 1
Columns: the plain-English version
OSHA 1926.758(b) requires at least four anchor rods per structural column during systems-engineered metal-building erection. [1]
This is a federal workplace erection minimum, not a method for choosing anchor diameter or foundation dimensions.
Worked calculation
Six structural columns × four rods equals 24 rods at that stated minimum. Engineered drawings may require more.
Start by separating the definition from the dimensions or requirements on a specific project. The reference below provides a concrete fact, its limits, and a practical example.
