SAP2000 moving load- is it for one vehicle per lane or more?

[Grendizer]

Dear all

It's being a week now I am reading between the lines in SAP manuals, watching their videos, checking internet resources, without success.

The question is simple though: how many vehicles SAP is engaging in each lane to calculate its 'Moving load load cases"


I read from help: " 'Moving load' load cases compute influence lines for various quantities and solve all permutations of lane loading to obtain the maximum and minimum response quantities."

However, at many paragraphs, SAP says: only one vehicle at a time (in a lane) is considered.

Then, at design time, automatic combo generations, the Moving load cases are directly incorporated along DL, Wind, etc, as if they are complete loading along the full span of the lane, and not just one vehicle study.

I ask you to help me solve this issue, if someone knows the answers.

Ok I know the answer, but it is said no had shown interest.

Moving load has option for Trailing and Leading Uniform loads, so load can be same like
AASHTO recommandation...
