Project Profile: Yan City Footbridge – A Lotus-Inspired Architectural Marvel
Location: China
Overview: The Yan City Footbridge is an iconic pedestrian bridge renowned for its unique design that emulates the elegance of a lotus flower. This architectural masterpiece not only serves as a functional crossing but also stands as a symbol of aesthetic harmony, blending seamlessly with its natural surroundings.
Structural Components & Detailing
- Primary Frame:
- Custom-fabricated two-way steel truss system with 3D curvature to simulate lotus petals
- Integration of cantilevered canopy arms and radial box girders
- Secondary Structure:
- H-section beams (Q355B) for support ribs
- Cold-formed light steel tubes (Φ60–Φ108 mm) for skin frame articulation
- Hidden connection systems to enhance visual continuity
- Foundation & Supports:
- Reinforced concrete pile caps with embedded base plates
- Vibration-isolation pads and thermal expansion joints for deck stability
Technical Specifications
- Material Grade:
Q355B for the primary structure; Q460C used in cantilevered and high-stress areas for enhanced load capacity. - Welding Standard:
Fabricated under AWS D1.1 and ISO 3834-2 certifications, utilizing full-penetration welds for structural reliability. - Anti-Corrosion Protection:
Dual-layer coating system with epoxy zinc primer and fluorocarbon topcoat, providing over 20 years of weather resistance. - Decking System:
