Herewith we publish intermediate results of our work on the Bullet Constraints Builder. This report is an extract of a much larger study of comparisons between the three simulation methods: DEM, FEM and AEM. This main study is for the time being restricted and it will only be published at a later stage. We are happy that we got green light to disseminate an extract with text content that was created by Laurea University of Applied Sciences.
In this report our simulation results are compared with well documented real collapse cases: The demolition of a simple beam, a mid-size column-slab assembly, and the destruction of the Pyne Gould Corporation building by an earth quake. The good agreement between simulations and reality is encouraging.
