Overmod That’s exactly I will do. Standard design live load vehicles on corrugated pipe can be mostly broken down into the following three groups: I have model 3D, so I will distribute live load on the beam like this: On the deck we have 2 rails, so Cooper E80 will divide 2 each rail. Our community is FREE to join.

This means that there are two loadings that need to be checked. I was able to get one planned measuring event where I could control just which loadig was over the reference location. HL loading is representative of the worst case between these two loading scenarios.

Figure Cooper Load Configuration for Bridges

I will model FEM and I will apply load in this. Students Click Here Join Us!

The answer is easier than you would expect. Others are more qualified to answer this. This is the industry’s manual of recommended practices for design and rating of steel structures.

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. Now I’m try to distribute live load on each beam.

I have already modelled it with static line loads based on AREMA procedures, however, now I have to perform some dynamic analyses. Download Now Defense manufacturing is all about project manufacturing and project accounting. Overmod Member since September, 6, posts.

My preference would be structural. This loading consists of kip axle loads spaced 5 feet on centers. Posted by Tran Anh on Sunday, November 11, So I want to ask experts like you, Paul, Steve I was taught that it’s ‘inherent’ in the idea of Cooper rating that it’s like the cantilever analogue of ruling grade: Are we must apply this train on all the bridge?

Calculation Live load with Cooper E80

Tran Anh Member since November, 7 posts. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I worked with John for many years at CP. Login or Register Customer Service.

If you have a example for this calculate, it’s so nice. For section transverse I have 4 I-beam so I will distribute this live load Cooper E80 cooepr this beam like this: Do you have example for calculate by hand or word?

I’m checking truss steel bridge railway It was built s. It is ok or not. 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.

I think you are reading too much into this. I don’t know it’s bad or good. I suspect these are relatively slight compared to effect of longitudinal loads and would be considered part of the factor of ckoper rather than explicitly included. Figure 1, above, also shows the design tandem. Randy Stahl Member since June, From: Vehicular live loading on the roadways of bridges or incidental structures, designated HL, shall consist of a combination of the: Sorry the first time is always difficult for me.

Yes Overmod, That’s exactly what I’m doing. Sign up for our email newsletter.

I almost always use examples from existing charts and graphs. Cover over the culvert was loadinng 3 feet. Design truck HS20 or design tandem, and Design lane load 0. Member since October, From: The axle spacings engine and train are specified — same? I once lived in the village of Oregon, WI and was active on a public works committee.
