Bridge collapse in Miami- Simulation with the BCB

Video: by courtesy of Kostack Studio

Blender and the BCB were used to model and simulate the bridge that collapsed in Miami in a speed modeling challenge. Due to the lack of precise technical drawings the Bridge was reconstructed on the basis of high resolution drone images. The element properties were estimated from close up photographs of the bursted reinforcement. The bridge was built and simulated in Blender in just 24 hours.

Even though the bridge model is only estimated and the BCB has not yet formulation for pre-stressed concrete it is interesting that the damage occurred about at the same location as it happened in reality. It is to be expected  that under evenly distributed loading damage happens at the truss diagonals with the biggest internal angle,  see image below.
