    How are rail cars load rated and what does that load rating mean when rail cars are used as bridges?

    SRE...have down loaded your suggested paper and pursued same. Looks to be right on point. Well read in detail. Thanks.

    How are rail cars load rated and what does that load rating mean when rail cars are used as bridges?

    There is a wood deck across the two cars but in my judgement the load transfer would be negligible. Currently because of the approaches to the bridge most traffic across the bridge goes down the middle and the load is approximately shared, approximately half on each structure. I fully...

    How are rail cars load rated and what does that load rating mean when rail cars are used as bridges?

    All...I should provide some context for my initial question. The rail car bridges have been in place 20 plus years. They have had loads cross them estimated to be 80,000 lbf many times over that 20 years. Mostly concrete trucks. They may have been load rated but if so I am unaware of it. My...

    How are rail cars load rated and what does that load rating mean when rail cars are used as bridges?

    Thank you all for the information and insights. It has been very helpful. I will go forward with the assumption that the loading was assumed to be uniformly distributed.

    How are rail cars load rated and what does that load rating mean when rail cars are used as bridges?

    PEinc...Thanks for the quick analysis....Lets say it is a cement truck with most of the weight over the rear axles. I assume in this case your analysis would say the bridge is overloaded? Are you pretty sure about the uniform loading assumption for rating the capacity? This makes a big...

    How are rail cars load rated and what does that load rating mean when rail cars are used as bridges?

    I am part of community that has a private bridge that consists of two flat bed rail cars suspended from concrete abutments. The side of each car has a capacity of 150,000 lbf given on the side of the car. My question relates to the assumptions that were used to calculate this capacity. Was a...
