1. A truss structure with a span L and a beam depth H, the truss comprising:
a main part,
wherein the main part comprises:
a bottom chord;
a planar top chord with a longitudinal centerline and having webs connecting between the top chord and the bottom chord, the top chord being separated from the bottom chord by the webs,
wherein
each web of the webs intersects with the centerline of the top chord at a top chord node,
wherein each web of the webs meets the bottom chord at a bottom chord node,
wherein at least two top chord nodes coincide with one another along the top chord;
wherein the bottom chord comprises a tension member,
wherein the bottom chord and the top chord are in compression, and
wherein the webs are comprised of a 3D-printed additive material; and
a shoe being provided at an end of at least one web of the webs distal from the top chord, said tension member being in a sliding relationship with respect to said shoe, said bottom chord being concurrently restrained from lateral movement relative to said at least one web by said shoe.
