Dear forum, I don't normally pay much attention to internal mass, but am modeling a warehouse which is relatively full of tall steel racking and products. These seem to represent a LOT of internal mass and should not be ignored. I have made an estimate of total internal surface area (which appears to be in excess of 2 million square feet for a 100,000 sq.ft. warehouse), but am now thinking in more detail about the properties of the internal mass.
- Racking is steel and has high surface / mass ratio
- The products which are stored on the racks are unknown, but almost certainly will be a composite of steel, aluminum, plastic. wood, etc. These products will be inside packages (e.g., boxes) that reduce overall surface area of the product, so surface / mass ratio is probably lower than the racking.
Have some of you done research on this topic? Have you made reasoned assumptions? studied the impact and found it to be too small to worry about?
Thanks for your insights.
