H-20 load rating for grating?
H-20 load rating for grating?
(OP)
I'm trying to select heavy duty grating capable of carrying H-20 highway loading from manufacturer catalogs. The catalogs ask for a specific concentrated load or ultimate load rating. I'm having trouble determining what Ultimate or Concentrated load on the grating is produced by H-20 vehicles to find the max span and bar sizing. Any help is greatly appreciated.
Thank You,

One strange thing about grating loading. An H-15 wheel loading sometimes controls over an H-20 due to its smaller footprint.

Here is a fairly good summary: http://www.ce.memphis.edu/3121/pdf_notes/notes_06c.pdf
Also you may want to get the free .pdf downloads from the metal grading bar trade association:

They do not answer your question but have good background information (probably similar to the catalogs you have).
A final thought - be sure to consider banding the grating for your heavy duty application.
