In this paper, effects of a loading direction and an existence of partially-complete cells on the mechanical properties of lattice structure are discussed based on theoretical and numerical stress analysis, FEM. By comparing the relative mechanical properties (initial stiffness E^* and plastic collapse strength σ^*_<pl>) per unit relative density, it has been shown that the BCCZH lattice structure is the bending-dominated structure, and the mechanical properties of BCCZH are similar to those of BCC structure. Also, the f_2BCC structure is more stable and offers a superior mechanical response than the other lattice structures. Moreover, the effect of partially-complete cells on mechanical properties is discussed, and using an approximate solution, the parameters E^* and σ^*_<pl>, for structures with partially-complete cells can be estimated from those for complete lattice structures.
