Hi. I want to simulate a fire and apply it on a reinforced concrete structure in Transient Thermal Analysis. I'm going to use the ISO834 fire Curve (gas temperature vs time curve). I don't know how the ISO 834 Curve would be applied on the structure. Inputting the ISO 834 Curve directly on the surface as the temperature isn't really proper.

Since it says the temperature in the fire curve is the fire temperature, you should be able to specify it in a convection boundary condition in tabular data with multiple time points.

I'm not sure what you would use for the convection coefficient, if you want to stick with a constant or if you also have some testing data for that.

If you need a very accurate analysis, you should be using a fluid solver.
