Railroad Bridge Analysis and Rating
Posted 07 December 2011 - 08:01 PM
My company recently got some projects for railroad bridge inspection, rating and analysis.
I can barely find references. Anyone knows where can I find examples? Thanks a lot.

Inspections differ between RR company. Here are some federal safety standards regarding inspections:
Do you have any type of structural analysis software? We use MDX software for steel bridges.

We used Merlin Dash and Staad for steel bridge analysis. However they cannot handle any railway code related design.
Merlin Dash has code checking for AASHTO, it is very handy for highway bridges but not railway bridges.
I need to figure out rating for different types of railroad bridges such as through girder, truss, railtop, concrete deck, prestress beam, stone arch and concrete arch.
Do you also know any references for concrete or arch railroad bridges? Thanks a lot.

We had some work with Railroad before but mostly inspection and rating of overpass bridges using highway loads.
It is a good opportunity to really get familiar with AREMA now. There are several bridges (around 10 different types) to be analyzed/rated.
If there is any specific problem I will let you know. Thanks a lot.
