A box truss is a structure composed of three or more chords connected by transverse and/or diagonal structural elements.
By using what are in effect stiff panels in a cylindrical arrangement the resulting structure can have a high resistance to axial torsion (twisting along its long axis) and a higher resistance to buckling in its highly loaded sides.
When finished as an open structure the truss will be less subject to wind drag and to aeroelastic effects than would a completely enclosed structure.
