In heavy industrial construction, steel is expensive and heavy. Over-designing a hundred anchor bolt chairs on a massive tank farm wastes thousands of dollars. The AISI formulas allow you to find the ideal thickness for the chair's top plate, vertical stiffeners, and the vessel shell itself. 3. Prevents Localized Shell Buckling

): Must be tall enough to distribute the load without overstressing the shell. Typical heights range from 6 to 33 inches depending on the bolt size and shell thickness. Top Plate Thickness ( In heavy industrial construction, steel is expensive and

Next time you detail a moment frame, a heavy column, or even a light industrial rack, remember: The anchor bolt chair is not a cost to be minimized. It is a component to be optimized. And the path to optimization is paved by .
The primary function of an anchor bolt chair is to transfer the massive uplift and overturning forces generated by wind or seismic loads from the anchor bolts into the vessel shell.
