Abstract: This thesis proposes and develops two novel lightweight tensile restrained structures: Tension Strip Structures (TSSs) and Deployable Cable Chain Structures (DCCSs). In TSSs, tensile restrained arches are used to shape a column-like member resisting axial load rather than resisting gravity load in conventional arch structures. The buckling resistance of slender structural systems may be significantly improved by restraining the compression members laterally by tensile membrane. Both numerical and experimental investigations have been performed to understand the structural behaviour of TSSs. In DCCSs, cable restrained compressive elements consisting of discretized struts forming barrel vault or dome shapes providing enclosure space. Nonlinear inelastic analysis has been carried out for DCCSs to predict the load-displacement behaviour up to the maximum load. Comparison with other existing foldable shelters indicates that DCCSs have high structural efficiency in terms of strength to weight ratio.
