An iso-truss structure ( 10 ) includes at least two helical components ( 30, 32 ) and at least one reverse helical component ( 34 ) attached thereto with opposing angular orientations. Each helical and reverse helical component preferably includes at least four elongate, straight segments ( 22 ) rigidly connected end to end in a helical configuration forming a single, substantially complete rotation about a common axis ( 14 ) forming a first square cross section. The structure may further include at least two rotated helical components ( 80, 92 ) and at least one rotated reverse helical component ( 98 ) which are rotated with respect to the helical and reverse helical components forming a second square cross section, rotated with respect to the first. The structure may be straight, curved, flexible, or form angles. |
