Due to the progress in urban planning, our country has experienced an increase in the expansion of transportation networks, which has exposed the road network to the risk of rockfall disasters. A wire supported rockfall protection fences have been constructed as one of countermeasures. But it is necessary to examine the performance of a wire supported rockfall protection fences using impact load experiments. This study examined to simulate full scale collision experiments of wire supported rockfall protection fences using elasto-plastic analysis. Additionally, the weak points of the rockfall protection fence were investigated using simulation. The results reproduced the deformation response observed in the experiments with maximum tension falling within the safety range. Moreover, it was shown that analysis parameter of reproductivity analysis was feasible for analysis with different collision positions.
