Deployable structures have the ability to transform themselves from a small,
closed or stowed configuration to a much larger, open or deployed
configuration. Mobile deployable structures have the great advantage of speed
and ease of erection and dismantling compared to conventional building
forms. Deployable structures can be classified according to their structural
system. In doing so, four main groups can be distinguished: spatial bar
structures consisting of hinged bars, foldable plate structures consisting of
hinged plates, tensegrity structures and membrane structures.
Because of their wide applicability in the field of mobile architecture, their
high degree of deployability and a reliable deployment, two sub-categories are
studied in greater detail: scissor structures and foldable plate structures.
Scissor structures are lattice expandable structures consisting of bars, which
are linked by hinges, allowing them to be folded into a compact bundle.
Foldable plate structures consist of plate elements which are connected by line
joints allowing one rotational degree of freedom. A wide variety of singly
curved as well as doubly curved structures are possible.
Although many impressive architectural applications for these mechanisms
have been proposed, due to the mechanical complexity of their systems during
the folding and deployment process few have been constructed at full-scale.
The aim of the work presented in this dissertation is to develop novel concepts
for deployable bar structures and propose variations of existing concepts
which will lead to viable solutions for mobile architectural applications. It is
the intention to aid in the design of deployable bar structures by first
explaining the essential principles behind them and subsequently applying
these in several cases studies. Starting with the choice of a suitable geometry
based on architecturally relevant parameters, followed by an assessment of
the kinematics of the system, to end with a structural feasibility study, the
complete design process has been demonstrated, exposing the strengths and
weaknesses of the chosen configuration.
