Pre-Stressing Timber-Based Plate Tensegrity Structures

Tensile structures occur in numerous varieties utilising combinations of tension and compression. Introducing structural plates in the basic tensegrity unit and tensegric assemblies varies the range of feasible topologies and provides the structural system with an integrated surface. The present paper considers the concept of plate tensegrity based on CLT plates (cross-laminated timber). It combines the principles of tensegrity with the principles of plate shells and is characterised by a plate shell stabilised by struts and cables. The paper deals with material aspects and robustness of timber-based plate shells and outlines needs, methods and effects of controlling cable stresses for secured capacity, form and function of plate tensegrity.Tensile structures occur in numerous varieties utilising combinations of tension and compression.
