Upper Steel Structures (ACC, Hood Type Building) with Bird Protection Net at GEX 3300-Emir-33MW Geothermal Power Plant, Turkey
1. Scope
2. Key Components
Channels: UPE/UPN profiles for primary support beams.
Angles: L-shaped sections for bracing and secondary supports.
Plates: Connection plates, gussets, and base plates (thickness as per load calculations).
Bird Protection Net:
Mesh material (e.g., stainless steel or UV-stabilized polypropylene, if unspecified).
Attached to the steel framework via galvanized clamps or hooks.
3. Material Specifications
Hot-Dip Galvanizing: Coating thickness ≥ 85 µm (ISO 1461 compliance).
Post-fabrication galvanizing to ensure full coverage.
Fasteners:
Bolts: Grade 8.8 (M12–M24), hot-dip galvanized.
Nuts/Washers: Grade 8 galvanized, matching bolt specs.
4. Design Considerations
Wind loads (per Turkish Building Code/EN 1991-1-4).
Seismic loads (Turkey Zone 2/3 compliance).
Dead load of structure + netting.
Corrosion Resistance:
Critical for geothermal environments (high humidity/H₂S exposure).
Double-check galvanizing quality at weld-free zones (if any).
Modularity:
Pre-drilled holes for bolted assembly; tolerance ±2mm.
Allow for future maintenance access.
5. Fabrication & Installation
Cut, drill, and label all steel components.
Galvanize after fabrication to avoid coating damage.
Pre-assemble modules for quality checks.
Installation:
Erect primary steel structure using cranes.
Bolt connections tightened to 70% of proof load (per EN 14399).
Attach netting with tensioning systems to prevent sagging.
6. Compliance & Testing
ISO 1461 (galvanizing), EN 1090 (steel fabrication), EN 1993 (design).
Turkish seismic codes (TEC 2018).
Quality Control:
Mill certificates for steel.
Coating thickness tests (magnetic gauge).
Bolt torque testing (30% random checks).
7. Challenges & Solutions
Oversize bolt holes by 2mm to accommodate zinc buildup.
Net Durability:
Specify nets with anti-corrosion coatings if non-stainless.
8. Deliverables
Galvanizing inspection reports.
Bolt/nut certification (Grade 8.8).
