“…Along these lines, this article examines six hybrid cable bending-active units in their form-finding as well as in their subsequent load-bearing stage. Preliminary investigations of the units’ behaviour based on regular mesh modelling of the elastic members have been conducted by the authors in Alexandrou and Phocas 15 and Phocas and Alexandrou. 16 This study aims at a comprehensive analysis of the units’ behaviour, whereas the elastic members have been modelled as beam elements.…”

This article examines the structural behaviour of six structural units composed of single, simply paired and pairedinterconnected bending-active members, coupled with a single cable element. The form-found curvilinear shape of the members is achieved through fastening by contracting auxiliary elements, as well as through further deformation by decreasing the cable's length. The overall structural behaviour of the units is investigated based on a step-by-step finiteelement analysis. All units are evaluated with regard to the components' stresses and deformations developed during the form-finding process and subsequent external vertical loading, for different possible section thickness values of the elastic members.
