In this paper, to properly evaluate the dynamic response behavior of diamond-shaped wire-net under falling-weight impact, 3D elasto-plastic impact response analyses were performed taking the diameter of the wire and the mass of weight as variables. Here, wire-net and wire-rope were modeled by using beam element and cable element, respectively. 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 using the proposed method; 2) although the tension forces of vertical wire-ropes were tending to be overestimated, the horizontal ones may be properly estimated; 3) the deflection of the wire-net may not be affected by the falling angle of the weight.
