IBC Live Loads-Areas subject to trucking

[mrengineer]

IBC 2003 Table 1607.1, item 33, "Sidewalks, vehicular driveways and yards, subject to trucking" specifies 8000 pound concentrated load. AASHTO HS20 loading is 32 kip axle load (16 kips at each of 2 tandem wheel locations). Seems like IBC is a little deficient in their requirements?

I agree! It should say small trucks (HS12-44)

 

[miecz]

I agree. I use AASHTO HS-20 loads for areas exposed to truck loads.

ICC is taking IBC code proposals for the 2007/2008 cycle. Visit iccsafe.org. Submitting a proposal is not very difficult. Just a matter of filling out a form in a specified format and emailing it to ICC.

Perhaps they are taking the axle load distributed to four tires per axle.

 

[miecz]

More likely, they are thinking light truck, as in H-10, which has an 8,000 lb maximum wheel load. This would exclude dump trucks, concrete mixers and tractor trailers.

I seem to recall that they specify somewhere that a concentrated load is assumed over, say, a 30" square area- so an 8,000 lb concentrated load in that case would not cover dual wheels on a semi.

Footnote "e" puts the 8,000 lb load over 20 square inches.
