trying to come up with cost effective portable temporary bridge design 12 x 12 feet. All steel construction and steel plate deck welded directly to beams.
where/how/tables? do i calculate the minimum thickness required of the steel deck? one way-two way loading, all tables and most spreadsheets and formulas i find are for uniform loading per square feet... not sure how to translate that intelligently into a 20"x10" 16,000 lbs point load from wheel/s. (32000 total axle load at one time in bridge.
so far using beams at 17" on center. 7/16" a36 plate? seems thick... 3/8"?![[2thumbsup] [2thumbsup] [2thumbsup]](/data/assets/smilies/2thumbsup.gif)
any thoughts?
