ELLA Braking load

Hi

I am applying ella traffic load based on IRC 6 loading where I need to consider height of the vehicle for braking load so that it can induce moment in the 5 span continuous beam bridge. However, when I am defining the height of vehicle based on HSA using LANE in sofiload, it does not give me the results.

Can you tell me how I should do it. I also used P9 when defining the vehicle using TRAI command. It also does not give me results.

And also should i consider height of vehicle from cg of the beam cross section or from the sln defined for the beam where I have put the cross section with eccentricity.

Also can someone tell how to get bearing forces in ELLA, because when I am defining RSET it says the run analysis is through non linear and it gives error for it.

If you upload a simplyfied system and explain where you expect what perhaps I can help.
