In this paper, to properly evaluate the dynamic response behavior of diamond-shaped wire net used for rock protection structures, three dimensional elasto-plastic impact response analyses were performed. Here, two types of modeling for wire net were employed: simple membrane model and detailed beam model. An applicability of the proposed analysis methods was confirmed comparing with the experimental results. From this study, following results were obtained: 1) the central deflection of wire net can be appropriately estimated by applying both models; 2) although the tension forces of vertical wire-ropes were tend to be overestimated, the horizontal ones may be properly estimated by using proposed method; and 3) the anisotropic deformation behavior of wire net can be properly estimated by applying beam model.
