The Vitruv Building Library

In order to supply rescue personnel with training material  a data base with pre-run collapse simulations was created. This building library consists of four building types that are archetypical representations of a number of commonly built structures:
1. Vitruv Building #2: a low apartment building
2. Vitruv Building #3: a high rise building with a square shaped floor plan and a center core
3. Vitruv Building #9: a high rise building with a rectangular floor plan and a center core
4. Vitruv Building #11: a historic, double wing brick building

Those four buildings have been submitted to various explosion and earthquake scenarios. Damages from detonations were defined and earthquakes with four ascending intensities from low to devastating were simulated.

This building library is expected to be extended in the future to not only serve training exercises but also allow more and more accurate predictions where hollow spaces will be formed in which victims can survive.

In the beginning the videos show a new useful BCB functionality: A mesh of the concrete rebar is generated following the definitions in the BCB´s Formula Assistant namely rebar position amount and sizes. This rebar mesh is only for diagnostics to detect obvious mistakes in the element settings and is not linked to the simulation routine.

We picked up our initial approaches (blog post from 20. Mai 2015) to visualize cavities and applied a modified version on the collapse debris mesh. We could prove that cavity can be visualized fast and directly  in Blender largely with Blender´s native inbuilt modifiers. The result can be seen in the last sequence of the videos.
