The Roman Bridge-Builder: Some Aspects of his Work

This paper describes the design and execution of Broadgate Exchange House, an exciting steel structure in London. This structure uses four tied-arches to clear span an entire office building 78m over a congested railroad track site. An important visual aspect of the building is the use offire engineering principles to allow the perimeter structural steel to be exposed. Special features include redundancy, corrosion protection, behaviour under patterned loads, and buckling analyses. This special structure combines the diverse roles of a bridge and an office building into one system with a clarity of expression which is the focus of the architecture. H. Iyengar, W.F.
