CFRP dome
The CFPR dome consists of three layers, marking the first use of CFRP as an earthquake-resistant structure in Japan.
CFRP, a plastic reinforced with carbon fibres, boasts exceptional lightweight properties, with a specific gravity roughly one-fifth that of steel, while maintaining comparable strength. This enabled the realisation of a 40m-span dome on a shallow foundation, significantly reducing the weight per unit area.
However, as CFRP is sensitive to temperature changes, thermal simulations were carried out to verify its load-bearing capacity in the high-heat, high-humidity conditions expected after the pavilion’s relocation to the Maldives.
A steel frame was integrated into the outer layer supporting the membrane structure, with CFRP pipes used in the second and third layers. Designed with relocation and reuse in mind, the pavilion not only prioritises safety but also emphasises environmental sustainability, exceeding decarbonisation benchmarks.
