An anchor bolt chair is a fabricated assembly welded to the base of a shell or column. According to the , a standard chair consists of:

): 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 ( aisi e 1 volume ii part vii anchor bolt chairs better

These chairs are considered "better" than alternative fastening methods because they effectively minimize secondary bending stresses in the shell by distributing loads through a rigid, box-like assembly. Core Components of an AISI Anchor Chair An anchor bolt chair is a fabricated assembly

Engineers using this manual must calculate several key dimensions to ensure the chair is "better" than a generic attachment: Chair Height ( Top Plate Thickness ( These chairs are considered

Welds between the vertical plates and the shell must be checked for combined vertical and horizontal loads. A 1/4-inch fillet weld is often sufficient, but larger bolts require detailed verification. Comparison: Chairs vs. Continuous Rings

Supports the nut and washer, transmitting the bolt tension into the vertical plates.
