Externally Post-Tensioned Deployable Timber Structures

The second CFTS Research Pavilion developed a new type of deployable timber structure, which uses an external post-tensioning deployment mechansism and a hybrid steel-timber structural component. The structure has been used at five (public and private) events around UQ and Brisbane.
