Dust loads on roofs


I didnt find any reference for the dust on roofs.

The only reference I found is the default values in SAP2000 which:

  1. Sand accumulation height in flat and curved surfaces equal to 20 cm in case of no parapets.
  2. Sand accumulation height in flat and curved surfaces equal to 120 cm in case of parapets decreasing with 45 degrees to 20 cm height 1m away from the parapet.
