| Heavy Duty Steel Design Criteria |
| The following pages show capacities on the basis of
vehicular load distribution and concentrated loading per foot of
grating width for a given span. Calculations for concentrated load
are similar in format to those for Light Duty Steel Grating shown on
page 73, except F = 20,000 psi. Calculations for vehicular loadings
are based on AASHTO Standard Specifications for Highway Bridges and
utilize the following formulas:
|
| NOTES: (1) For continuous spans, use continuity factor = .80. (2) **This distribution results in larger grating sizes for lighter trucks on shorter spans. Spans shown for H15/H20 reflect the more critical condition. (3) The fork lift wheel loads and load distribution patterns depicted above, generally, and only partially, represent the broad range of rubber-tired lift trucks available. For those applications falling outside of these examples, please contact the factory. (4) Wheeled vehicles with urethane tires should NEVER be used in conjunction with open grid bar grating. (5) HS20 is the same as H20 and HS15 is the same as H15. The “S” stands for semi-trailer.
