Lamellae Roof
ABOUT THE PROJECT
Lamellae Roof embodies an innovative bio-inspired approach to designing structurally efficient light-permeable roofs. This project adopts an advanced computational workflow to create a roof structure that minimises material use while being permeable to light, achieved through a topologically complex, non-orthogonal two-way ribbing system that aligns with primary and secondary stress moments. Its structural design complies with Eurocode serviceability requirements through the exclusive use of Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC), eliminating the need for traditional steel reinforcements. The engineering process was supported by high-resolution Finite Element Analysis, which iteratively refined the roof's bio-inspired shape to bear loads effectively without conventional reinforcements. The fabrication process utilises cutting-edge digital formworking and a subtractive manufacturing approach with robotically milled moulds. Material studies, including optical analysis of fibre distribution and tests for compressive and tensile strengths, enable precise structural assessments under critical load conditions. Lamellae Roof is designed as a reversible structural element for modular polyhedral structures, allowing for repetition and various spatial configurations. This modularity enhances the roof's versatility and application in different architectural contexts, promoting sustainability through reusable elements.
