The AREA ratings are coopet longitudinal only no allowance for transverse moments and in that respect ought to be like lane ratings. Do you have any experience, easy ways to create time-amplitude graph of high speed railways? Students Click Here Join Us! Cover over the culvert was about 3 feet.

Member since February, 1, posts. Order Ascending Order Descending. I once lived in the village of Oregon, WI and was active on a public works committee. I have already modelled it with static line loads based on AREMA procedures, however, now I have to perform some dynamic analyses. Sorry the first time is always difficult for me.

I almost always use examples from existing charts and graphs. So I don’t know exactly Cooper E80 working. By joining you are opting in to receive e-mail.

So I want to ask experts like you, Paul, Steve Same as PEinc, I’ve not seen it done though my experience here is limited. This loading consists of kip axle loads spaced 5 feet on centers.

COOPER E80 Dynamic Loading – Foundation engineering – Eng-Tips

Before, i just did simple concrete bridge. Standard design live load vehicles on corrugated pipe can be mostly broken down into the following three groups: Others are more qualified to answer this. This means that there are two loadings that need to be checked.

The Eng-Tips staff will check this out and take appropriate action. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Of course the crew engineer was not too pleased with this “fooling around” using his time, but the conductor, in charge of the train, was down in the tunnel with me and directed the engineer by radio.

Calculation Live load with Cooper E80

It turned out that many subsequent readings were made by the village, but the original readings before loadings always returned to the same stable numbers. Member since October, From: The design tandem shall consist of a pair of kip axles spaced 4 feet apart and the transverse spacing of the wheels shall be taken as 6 feet.

An illustration and some comments on the loading conditions can be found here: Promoting, selling, recruiting, coursework and thesis posting is forbidden. I was taught that it’s ‘inherent’ in the idea of Cooper rating that it’s like the cantilever analogue of ruling grade: Now I’m try to distribute live load on each beam.

There was a corrugated pedestrian “tunnel” under a railroad track in a filled embankment. My preference would be structural. Overmod That’s exactly I will do. So what should I do with Cooper E80?

HL loading is representative of the worst case between these two loading scenarios. And yes, HS20 live loading can control for an HL design check. Train traffic was light, but mainly an occasional train of loaded iron ore cars. The 2nd page has formulas for adding a percentage of loadingg live load for impact for concrete structues only.

Figure 1, above, also shows the design tandem. I think live load coopsr to momentshear and floor in cooper equivilant ratings.
