A new analytical model called spatially twisted wires is proposed in this paper with the objective of predicting three-dimensional stiffness matrix of a uniform space-filling wire-woven truss; wire-woven bulk kagome (WBK) and wire-woven bulk diamond (WBD). The stiffness matrix of order 12 by 12 for a helically wound wire is formulated using Castiglianos theorem. Effects of transverse shear forces and tangential thrust are taken into account. From numerical examples, the accuracy of this developed element is checked and shows that the WBD/WBK sub-unit cell stiffness is considerably dependent on the spatially twisted region.
