Validation - ATF Corridor

[Er9y714]

I would like to report a deviation between a figure and a validation fds input file. By the description of the experiment, FDS input seems more in line than the figure. Any thoughts?

According to Figure 3.1 in Validation Guide - 3.3 ATF Corridors Experiments, the stairs look different than the provided fds files below.
I believe the figure is sourced from : https://www.nrc.gov/docs/ML1433/ML14338A237.pdf

FDS file:

Figure 3.1:

Gypsum board thickness also deviates slightly.

I'll take a look at this, but next time, this would be more suitable as an Issue, in which case one person can be assigned to work on it. A Discussion post lacks this feature.

Good point. I will keep in mind. I had wanted to double check before raising the issue.

The test report on GoogleDrive shows the railing like structure on the stairs and calls it a flue space. Figure 6 in the report is a detail of the hallway soffit. No similar figure or text indicates that the second floor has a partial height wall overlooking the stairwell. The 3D drawing may be in error.

I am checking with the person who conducted the experiments.

I reached out to the person who helped conduct the experiments and he's going to dig up some photographs.

What a great opportunity!

I updated the drawing and some photos are attached.

Thank you very much for clarifying this!
