What is sydney Harbour Bridge as a case study?

Show answer

The Sydney Harbour Bridge (opened 1932) used about 53,000 tonnes of silicon-manganese structural steel, mostly rolled at Dorman Long in England with smaller quantities from BHP's Newcastle works. Connections are riveted, with around 6 million rivets in the structure. The arch was designed in compression using hand calculations of stress in every member. The choice of high-strength silicon-manganese steel over plain mild steel was driven by the need to keep section sizes within fabrication and transport limits of the day.
