LUSAS

LUSAS software was used by Network Rail to assist in its development of a prototype carbon fibre footbridge, allowing the design team to optimise the staged construction sequence, accurately predict structural behaviour, and evaluate key components using localised models.

A global model of the whole bridge allowed construction stages and dynamic effects to be assessed. Localised models included those for the carbon fibre stair ‘heels’, as used to support the stair and floor panels, and also for the main support heels, with their even more complex geometry.
