ABSTRACT

The annular crossed cable-truss structure (ACCTS) has been proven to be a promising structure with the advantage of lightweight, feasible constructability, good structural stiffness, reasonable behaviour under asymmetric load cases, the possibility to be used in a large span, and satisfying ability to resist disproportionate collapse. In this chapter, an integrated model which consists of a tensile membrane and the ACCTS is generated to validate the possibility of covering the ACCTS with a tensile membrane. Form-finding of the integrated model is done to evaluate the ability to maintain the shape and keep reasonable pre-stress. Based on the integrated model, the roof covering effects on the static behaviour and the ability to resist disproportionate collapse are discussed. The displacements and tensions from the integrated model are compared with pure ACCTS to discuss the roof covering effects on the structural stiffness, the behaviour under asymmetric load cases, and the ability to resist disproportionate collapse.
