An overview on the applications of mechanisms in architecture. Part I: bar structures

Abstract

Transformable structures in architecture have the ability to change morphology and readjust in response to varying conditions and needs that can include changing environment and climatic conditions, different functional requirements and emergency situations. Depending on how the transformation is carried out, transformable structures can be deployable or demountable, as a kit-parts system. Deployable structures can also be classified in four main groups: spatial bar structures consisting of hinged bars; foldable plate structures consisting of hinged plates; tensegrity structures; and membrane structures. In this paper, a review on the deployable structures based on rigid bar mechanisms will be performed.
