Torsion in Steel Beams This has raised further comment. Bing Choy writes: I’m a user of BS 449 as my design code but face a problem in dealing with the estimation of the effective length that is required to calculate the permissible compressive strength that makes the beam not suffer from buckling.
For some time the tubular column has been a staple of the construction industry. However, in its form as a concrete-filled tubular steel composite column, it now has attributes of speed and efficiency which can give it important advantages in multi-storey construction. Andrew Orton
A former china claypit at Bodleva, near St Austell in Cornwall, is being transformed into a 21st century ‘garden of Eden’ with an unusual and innovative structure. Two huge bubble-like domes (biomes), composed of steel spaceframes covered with triple layers of ETFE (Ethyltetrafluorethylene), have been constructed in the 60m-deep crater to form the world‘s largest greenhouse. It will become a protected environment for plants from around the world in settings which explain their habitats, uses and environmental importance to visitors. Kathy Stansfield
