The CED Dome is a pavilion design that explores structural efficiency through geodesic geometry. The dome is formed by weaving geodesic curves that originate from three points on a half-circle, gradually interlacing to create a continuous, self-supporting shell. Geodesic geometry ensures that each wooden beam remains untwisted in three-dimensional space, allowing it to be fabricated from flat wood boards with minimal processing.
To refine the design, we employed Karamba structural analysis software to test variations in dome height and radius ratios, identifying the optimal configuration to resist vertical loads. Comparative studies of alternative geometries—including catenary, spherical, elliptical, and star-shaped domes—were conducted to evaluate performance and deformation under pressure.
The dome’s structure is anchored by steel connectors embedded into concrete footers, protecting the beam ends from water exposure while ensuring long-term stability. Each structural element is composed of multiple layered beams, interwoven in alternating directions and fastened with bolts to enhance strength and resilience. A soft PVC membrane covers the dome, providing weather protection and shelter for users while maintaining transparency to natural light.
The result is a structurally rational and visually striking pavilion that merges advanced computational design, material logic, and environmental responsiveness into a cohesive architectural form.
