The length of the web plate is the distance between two wing plates in the I-beam.
According to the numerical simulation, the peak impact force and peak displacement response of the bridge pier in the vehicle collision process are reduced by more than 80% through the energy consumption of the energy consumption anti-collision device.
It should be noted that in embodiment 1, the beam 31 with a reduced cross section may be formed by splicing i-beams with web lengths gradually decreasing from two ends to the middle in the energy consumption direction.
