The two steel transmission towers that make up the Jintang-Cezi Overhead Powerline Link in China are the world's tallest, at 380 m (1247 ft). This video is a simulation of how these structures would collapse.

The towers have been accurately modelled in Blender at true scale, with the physics simulation being handled by the Bullet Constraints Builder add-on for Blender. Some simplifications have been made in the modelling of the towers, specifically, all steel members are solid when in realility they would be hollow. Nonetheless, the simulation is quite realistic.

The aim of this video is to bring awareness to the impressive size of these relatively unknown towers, and also give a glimpse at what would happen in the unlikely event of their collapse.

Thank you to @EarthquakeSim and @KaiKostack for their tutorials on using the Bullet Constraints Builder in Blender.
