| Failure Mode | Cause | Mitigation | |--------------|-------|-------------| | Shell buckling | Excessive compressive anchor load | Increase chair height or add stiffener rings | | Weld cracking | Fatigue or undercut | Use full-pen welds, post-weld heat treat if thick | | Bolt corrosion | Moisture in grout pocket | Seal with flexible sealant, use stainless bolts | | Grout crushing | Poor compressive strength or thin grout | Use epoxy grout with minimum 50 mm thickness | | Anchor pullout | Insufficient embedment or concrete blowout | Increase embedment, use headed anchors or anchor channels | tank anchor chair
