Trailer Design Criteria
Trailer Design Criteria
(OP)
I am load rating an industrial trailer (ie not on highway) for a client. Does anyone have any references or suggested design criteria for trailer design?
I have modeled the frame in RISA and multiple vertical loading combinations to determine what loads push it to AISC 13th allowable. I think AISC generally gives a safety factor of 2/3 on yield so how much additional safety factor (or load factor) is needed to account for dynamic or impact loading?
I have read this thread but still don't have something to hang my hat on. http://www .eng-tips. com/viewth read.cfm?q id=261920& amp;page=7

What is the useage of the trailer. I have done residentialo trailer frames and they were highway, subjected to 30 psf live loads sitgting and the dead load plus impact moving.
If these trailers are hauling gravel or equipment offroad, then it's Dead + Live + impact on the total of the two.

Mike - When you say 1.5 to 2.0, do you mean reduce the AISC allowable load by 1.5 to 2.0? Would this then be an equivalent safety factor of 3 to 3.5?
