Coker Operation
Structural Loads:• Extremely heavy
Operating Loads (full drums, proof loads)
• Comparatively light Dead Loads
• Resulted in full perimeter column repairs (instead of phased approach)

Deterioration Mechanisms
• Mechanical and impact damage
• Water and moisture cycles
• Freeze / thaw cycle
• Temperature differences
• Vibrations from equipment

Deterioration- #3 Stirrup spacing at 18” (many were damaged)- Structure vulnerable to brittle column failure in seismic event- Code requires 6”- Heavy deterioration- No concrete cover in many spots

Repair strategy • Column Repairs phased based on
loading and accessibility. 3 different loading conditions:
• Fully loaded drums and derricks
• Empty drums
• Removed drums and derricks
• Installing new shear reinforcement
• Augmenting damaged reinforcement

Repair strategy • Stirrup spacing reduced
from 18” to 6” to meet current seismic requirements and increase column ductility
• Vertical reinforcement augmented
• Cathodic protection installed
• Higher strength concrete

Cathodic ProtectionAnodic Ring (Halo Effect)• Halo Effect phenomena is
associated with a repair area that is surrounded by “new” corrosion sites.
• Halo Effect is one of the primary reasons for shot-lived repairs.

Per IBC 2012 Section 1901 General:
• 1901.1 Scope. The provisions of this chapter shall govern the materials, quality control, design and construction of concrete used in structures.
• 1901.2 Plain and reinforced concrete. Structural concrete shall be designed and constructed in accordance with the requirements of this chapter.
Zone 1 is an outdated term to define seismic risk which has been replaced by the term “seismic design category” (SDC). The current SDC corresponding to Zone 1 is “B” per ACI 318-14, Table R5.2.2.
