Here, the steel net and wire-rope were modeled by using shell element and cable element, respectively. From this study, the following results are obtained: 1) the impact force and displacement at loading point can be appropriately evaluated by applying the proposed numerical method until it reaches maximum displacement; and 2) however, since the rebound behavior of protection net cannot be properly simulated, it is necessary to investigate the modeling of net and stiffness between net and wire-rope.}, pages = {657--663}, title = {水平に設置された落石防護網の耐衝撃挙動に関する衝撃応答解析}, volume = {23}, year = {2015}, yomi = {コムロ, マサト and ニシ, ヒロアキ and コンノ, ヒサシ and アラキ, ノブヤ and ササキ, テツヤ} }
