    The vibration behavior of a stay cable subjected to abrupt rupture due to lateral force was studied using model experiments. Based on the experimental results, the performance of an existing cable-stayed bridge was studied using numerical analysis in cases where stay cables are abruptly ruptured by lateral force. The experimental results show that the impact force currently recommended is insufficient. The impact force is more affected by the tensile stress of the cable during rupture than by the initial stress. The results of numerical analysis show that the cable-stayed bridge analyzed in this study lacks serviceability performance against losing multiple cables in a collision incident.
