Live Load Transverse Analysis

[Thoughful]

Hello everyone,

I am running a transverse moving load case along the bent cap. I am using Multi step vehicle live load pattern generation.

For one lane: I defined my start distance as 1.75 ft which represent the EOD.
For two lanes: I defined my start distance as 1.75+12ft (lane)

I am trying to figure the impact of it on the duration of loading. My understanding that the duration of loading is simply (span-start distance) / speed. Is my understanding of it correct?

Thanks!
