ABSTRACT:
Deployable structures and methods for assembling the same including a structural mechanism defining a columnar space comprising a plurality of structural members, a plurality of couplings and a plurality of tension lines, wherein each of the couplings interconnects three of the structural members and each of the tension lines interconnects one of the couplings and one of the structural members. Each of the tension lines interconnects one of the couplings and an end of one of the structural members not interconnected with one of the couplings. A columnar space, devoid of any structural members, is centrally located within the structural mechanism. Each of the couplings interconnects two of three structural members such that they are substantially aligned along their respective longitudinal axes and the third of the three structural members is interconnected such that its longitudinal axis is substantially perpendicular to the longitudinal axes of the other two structural members.
