Walking on Eggshells: Innovative Methods to Justify Reuse of a Historic Thin Shell Roof at Smithfield Poultry Market

This paper describes the pioneering original design and construction of the 1960s historic concrete shell structure of the Smithfield Poultry Market Roof in London, and the sophisticated and innovative method used to breathe new life into this unique structure. This method combines a first order reliability approach with an advanced digital workflow that enabled a detailed technical analysis of the as-built structure. This method demonstrated the structure can meet the modern-day performance requirements without the need for any strengthening works – the most sustainable outcome which allows this beautiful structure to continue its legacy.
