Impact included in deflection calculation
Impact included in deflection calculation
(OP)
When checking a support beam over a rail unloading pit for deflection should I be including the impact factor? I can't find anything in AREMA or the IBC.
Thanks you for any help.

Many years ago, my boss checked a railroad bridge by measuring it's deflection. The bridge had been rated for 5MPH by the worried owner, my boss ran a locomotive over it a 5MPH and recorded the deflection (It said the bridge was good). Just to see the effect, he had them run the locomotive over at 30MPH. The deflection gauge didn't see a thing, the load was gone before it had time to stress all the material.

Timing has a lot to do with the outcome of a rain dance.
