The American Iron and Steel Institute (AISI) addresses this specific engineering challenge in its comprehensive publication, . The Role of Anchor Bolt Chairs

Modern finite element analysis (FEA) often validates what the AISE committees knew decades ago through empirical testing and experience: point loads on concrete foundations are destructive. The chair assembly acts as a distributor, turning a sharp point load into a broad, manageable pressure zone on the concrete pier. aisi e 1 volume ii part vii anchor bolt chairs better

For decades, this AISI reference has served as the primary guide for designing the stiffened chair assemblies that connect anchor bolts to tank shells. Its prominence is solidified by its incorporation into the American Petroleum Institute's API Standard 650, "Welded Tanks for Oil Storage". Clause 5.12.6 of API 650 explicitly states that an acceptable procedure for anchor chair design is the one outlined in "AISI Steel Plate Engineering Data, Volume 2, Part 5, 'Anchor Bolt Chairs'". While API 650 references Part 5, the design methodology in the referenced AISI data is widely recognized by the industry as the guidance within "Part VII".
