E80 cooper loading
(OP)
Trying to design the thickness of a liner inside a 12inch cast iron. 8ft cover from tracks to water main. In the contract it states that it is to be designed to E80 cooper loading, use 2600lbs/ft. What does this mean 2600lbs/ft mean? 2 tracks of total 34ft in width based on the blue prints. When I use the table, it gives me 11.11 psi for depth of 8ft using E80, but how does this clause that states 2600lbs/ft change this number. Thank you





RE: E80 cooper loading
I cannot tell you exactly what the specifier means without further information by the "2,600 lb/ft" you state, nor for that matter how it necessarily relates to design for all conceivable effects on any "liner"; however, I believe that number is probably quite close to a sum of the level of live loading pressure you say is applicable at pipe depth (I guess from such integration) plus earth load pressure at pipe depth, converted to a load per foot on a 12"size pipe.
