Coopers E90 Train loads
Coopers E90 Train loads
(OP)
I have a xerox copy of parts of a chart for lateral pressures due to a Coopers E80 Train Load. However, the owner requires a temporary shoring system (soldier pile wall) to be designed using a Coopers E90 Train Load. Could some one please point me to where I can find these charts?

Your charts (presuming they only show the live load effect so we don't have to account for not scaling the dead load pressures) can simply be scaled upwards by 12.5% to get the equivalent E-90.
I don't know the specifics of your situation, but even on a heavy haul mainline track, it seems to be overkill to design a TEMPORARY shoring system to such a high standard since current North American rail traffic (heaviest 286 kip cars = 71.5k axels) rates in the vicinity of E-60-75, depending on what they are running on.
Also, don't forget to use the alternative cooper loading cosnsist of four axels(100 k axels for E-80 = 112.5k axels for E-90)

I think you're in the right forum, wrong thread. Post a new thread topic.
