Most of the structures were built to be stiff and tough so that the floors support furniture, roofs divert rain, and walls block gusts for the occupants. However, it is not always the case. Some structures were built with moving, and some were built for moving. The second category has instances such as movable bridges, dynamic shading, retractable roofs, but this is not the main focus of this article. The first category refers to the structures that were initially built in alternative forms then be transformed into another configuration. I shall bring some examples for you.
Palau Sant Jordi, Barcelona, Spain, opened in 1990.
It is an indoor arena which has hosted multiple sport and culture events including the 1992 Olympic. Its roof was built in several inter-connected segments then were lifted to the current position. The following photos show the process.
Izumo Dome, Izumo, Japan, opened in 1992.
It is an indoor arena which has hosted multiple sport and culture events including the 1992 Olympic. Its roof was built in several inter-connected segments then were lifted to the current position. The following documentary video shows the push-ups of the scale model (6:50) and the full-scale structure (10:20).
Millau Viaduct, Millau, France, opened in 2001.
The deck of the bridge is at an extremely high position which prohibits conventional construction method. Instead of vertically lifting the deck, the deck was constructed on the side and pushed into the final position.
I am still searching for more information and details about these works. If you happen to any relevant reference, please kindly drop me some keywords.
