Rainforest Biome of Eden Project in Cornwall, United Kingdom
The Eden Project in Cornwall, United Kingdom is a complex of two huge biome buildings consisting of several domes and outdoor gardens. Inside the biomes, there are several thousand species of plants collected from many diverse climates and environments, which serve for biological studies and exhibitions. The Rainforest Biome was built in the second phase of The Eden Project’s development. It is kept at a tropical temperature and moisture level and covers over 1,000 varieties of tropical plants.

The original vision for the project belonged to anthropologist and archaeologist Tim Smit.
The architectural design was done by Nicholas Grimshaw and Partners from London, after preliminary structural design by MERO.
The biome structure is a hex‑tri‑hex space frame with two layers. The frame structure consists of steel tube segments that were connected using bolted joints.
The external cladding panels are hexagonal and pentagonal in shape and consist of inflated membrane cushions made of three layers of ETFE foil, which maximize the ultraviolet light from the sunlight needed by the plants. Thus, it is possible to simulate the environment for the tropical plants very well.
The structure was created in CAD and imported into structural engineering software RSTAB.
The load cases and result combinations comply with the British standard BS 5950. A calculation according to the second-order analysis was carried out.

- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
- How can I efficiently define line hinges on several surfaces?
- How do I include the overstrength factor(s), Ωo in the ASCE 7 load combinations?
- How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
- How do I create a user-defined fabric?
- How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
- My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations?
- I do not see the seismic load cases in my generated ASCE 7 load combinations (COs). How do I add them?
