Hello All,
My name is Nandor Mago and I will be presenting at the 2014 SIMULIA Community Conference. The paper and presentation I have prepared will show how to perform effective fire simulation on reinforced concrete composite slabs using a re-entrant profiled steel sheet, and to assess the fire resistance rating.
There are a number of challenging questions in performing these simulations such as:
- Should a solid model be used to accurately represent the slab re-entrant profile or is an equivalent flat shell representation sufficient?
- How to determine the temperatures in the structure due to fire?
- If shell elements are used, how to model in Abaqus/CAE dissimilar temperature-time (T-t) curves through the slab depth, since the bottom surface, close to the fire source, heats up at a much higher rate than the top surface?
- Whether to use Abaqus/Standard or Abaqus/Explicit?
- If Abaqus/Explicit is chosen (due to issues with concrete cracking), how to perform a quasi-static simulation with time periods of couple of hours, while the stable time increment is in order of 1e-6 seconds?
If you find these issues of interest to you, join us for this presentation at the SCC.
I look forward to seeing you there!
