Anchor Bolts Ductile Design Philosophy in Petrochemical Facilities
The concept of ductile design for anchor bolts aims to control failure by allowing the anchor or attachment to yield gradually, preventing sudden collapse. Ductile failures enable steel to absorb energy and elongate, crucial for seismic applications. Anchors must be designed to be governed by the tensile or shear strength of ductile steel. Ductile design is required for critical loads, especially in seismic or blast resistance applications. Key requirements include ensuring concrete capacity exceeds that of the anchor and selecting ductile steel. If requirements cannot be met, methods to increase concrete or shear capacity can be employed. Reinforcing bars or shear lugs can also be used to achieve ductile design.
