Finite element design of the connection of barriers for the protection of crowded places

The terrorist attacks in Europe have highlighted the problem of safety in public places. It is enough to run a vehicle at high speed towards the crowd to cause a large number of injuries and victims. In response to these phenomena, the Municipalities have perimetered sensitive areas with protection tools. The authors of this work have already designed a mobile anti-terrorism barrier capable of stopping 3500 kg and 7500 kg vehicles with a speed of 64 km/h in a few meters. In this work, the connection of two barriers by ropes is designed using Finite Element (FE) method to perimeter large areas with a small number of devices. Steel and Dyneema® ropes are studied, discussing the number of ropes and the dimensions needed.
