Hi! I am doing the girder analysis by hand. Thank you I calculated the aL. Could you elaborate on determining aW by lateral/torsional restraint conditions? Thanks!

Or if you know of any examples that would help me understand that would be greatly appreciated!

Could you provide some more information on how I can calculate these? Thank you!

I am designing the bearings for a railway bridge according to AREMA. I have been following AREMA Ch 15 but I am getting stuck on calculating the rotations. These are the variables I need to solve for but I am new at this so any help would be appreciated! aL = Relative rotation of top and bottom...

I am designing bearings for a railway bridge. Through my research I am designing steel reinforced elastomeric bearings at the fixed and expansion bearings. Is designing for a dowel in the fixed bearings a practical solution for this to limit translation? Also are there any limitations on having...

Thank you both. For calculating the sizing of these bearings are there commonly used sizes that are readily available or will they have to be made per design?

I am designing a rocker bearing for a railway bridge project and am struggling to find helpful guidelines on the procedure to follow. Does anyone have any suggestions?
