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.
: The guidelines cover various structures, including flat-bottom tanks, conical skirts, and small tubular columns. Design Considerations for Enhanced Stability aisi e 1 volume ii part vii anchor bolt chairs better
In the complex engineering of stacked vessel construction and elevated tank design, the transfer of loads from the superstructure to the foundation is the single most critical point of structural integrity. While the vessel shell and the foundation itself are often rigorously analyzed, the connection point—the anchor bolt chair—is frequently treated as an afterthought. The primary function of an anchor bolt chair
Anchor bolt chairs are required when supports must distribute high tensile or compressive loads into a structure's shell. Their primary purpose is to in the shell that would otherwise occur if anchor bolts were attached directly to a base plate. While the vessel shell and the foundation itself
