Engineers using this manual must calculate several key dimensions to ensure the chair is "better" than a generic attachment: Chair Height (
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 aisi e 1 volume ii part vii anchor bolt chairs better
Using the offers several advantages over simple gussets or direct bolting: Engineers using this manual must calculate several key
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 Comparison: Chairs vs
In the engineering of industrial storage tanks, pressure vessels, and tall columns, the transition of high tensile loads from anchor bolts into thin-walled shells is a critical structural challenge. (Steel Plate Engineering Data) provides the industry-standard methodology for designing anchor bolt chairs.
(minimum eccentricity) to ensure heavy hex nuts can be tightened without interfering with the shell wall.
