After the 2012 Olympics, London's Olympic Stadium was transformed into a multi-purpose venue with a new, much larger, roof.
The increased load required significant strengthening of the compression truss and V-columns which support it.
The gravity-stressed roof relies on the tension stiffness of the underlying cable-net for stability, resulting in a highly non-linear structure, which required a complex large-displacement and fully staged analytical approach.
The project was fast-tracked and the stadium re-opened in time for the Diamond League Athletics event in July 2015.
