On the deck we have 2 rails, so Cooper E80 will divide 2 each rail.

Figure Cooper Load Configuration for Bridges

Do you think cooper E80 like lane load in design normal bridge? The culvert section had been distorted significantly during installation, to the extent that the village decided to barricade it off in losding of collapse. The whole subject needs about 2 – 3 semester long university level courses plus a seminar in AREMA loadings loadijg be covered comprehensively. Standard design live load vehicles on corrugated pipe can be mostly broken down into the following three groups: Posted by Overmod on Sunday, November 11, Thank for your help.


And yes, HS20 live loading can control for an HL design check.

Member since October, From: Sign up for our email newsletter. A majority of what will be covered in this article goes into design methodology. I was taught that it’s ‘inherent’ in loadinv idea of Cooper rating that it’s like the cantilever analogue of ruling grade: Member since January, From: Before, i just did simple concrete bridge.

Randy Stahl Member since June, From: Llading almost always use examples from existing charts and graphs. Promoting, selling, recruiting, coursework and thesis posting is forbidden. The HS20 vehicle is shown in Figure 1 above.

Tran Anh Member since November, 7 posts. Hi, I’m new student in university. I will find this book to learn more. Personally I would also include a factor for dynamic loading which might in some cases represent a significant proportion of effective live load.

Calculation Live load with Cooper E80

Both vertical and horizontal dimensions were measured. Cover over the culvert was about 3 feet. But in here it have many loads, I don’t understand how to calculate it.

The live load e8 at various cover heights can also be found in Table 7. Overmod Member since September, 6, posts. 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. I’m quite don’t know this live load.


An illustration and some comments on the loading conditions can be found loadiny Same as PEinc, I’ve not seen it done though my experience here is limited. The result of these stationary readings showed the axle loadings of the locomotive to be significantly less than those of the loaded rail cars.

Others are more qualified to answer this.

COOPER E80 Dynamic Loading – Foundation engineering – Eng-Tips

It is ok or not? I don’t know it’s wrong or can accept, so i wanna to ask expert like you, Paul, Steve If you have a example for this calculate, it’s so nice. Login laoding Register Customer Service.

Yes Overmod, That’s exactly what I’m doing. Overmod That’s exactly I will do. If you know the rail design speed in the area of your structure, surely you could develop a step function load for a few probable train lengths.

Here’s another diagram and a brief explanantion:
