Maxima handling braking forces

Hi

I’m creating a loadtrain in sofiload and I have the option to add braking and transverse loading to the train. I can’t however figure out how maxima handles this?

I have different load combination factors on the vertical and horizontal vehicular loads, so I need to be able to assign this.

Do I have to define multiple loadtrains for each component, or can maxima handle the different loadfactors in the same loadtrain by itself?

Option 1:

LC no 100 titl 'Klasse 50'
  TRAI type 'user' widt 3
  TRPL p 65  pb 13.4 pw 3.3 nw 2 b 2 bw 0.6 lw 0.2        
  TRPL p 65  pb 13.4 pw 3.3 nw 2 b 2 bw 0.6 lw 0.2 a -3.2 
  TRPL p 65  pb 13.4 pw 3.3 nw 2 b 2 bw 0.6 lw 0.2 a -1.4 
  TRPL p 109 pb 22.5 pw 5.6 nw 2 b 2 bw 0.6 lw 0.2 a -4.5 
  TRPL p 118 pb 24.3 pw 6.1 nw 2 b 2 bw 0.6 lw 0.2 a -1.4 
  TRPL p 109 pb 22.5 pw 5.6 nw 2 b 2 bw 0.6 lw 0.2 a -1.4

Option 2:

LC no 100 titl 'Klasse 50'
  TRAI type 'user' widt 3                 
  TRPL p 65  nw 2 b 2 bw 0.6 lw 0.2       
  TRPL p 65  nw 2 b 2 bw 0.6 lw 0.2 a -3.2
  TRPL p 65  nw 2 b 2 bw 0.6 lw 0.2 a -1.4
  TRPL p 109 nw 2 b 2 bw 0.6 lw 0.2 a -4.5
  TRPL p 118 nw 2 b 2 bw 0.6 lw 0.2 a -1.4
  TRPL p 109 nw 2 b 2 bw 0.6 lw 0.2 a -1.4

LC no 101 titl 'Klasse 50 brake'
  TRAI type 'user' widt 3                 
  TRPL pb 13.4 nw 2 b 2 bw 0.6 lw 0.2       
  TRPL pb 13.4 nw 2 b 2 bw 0.6 lw 0.2 a -3.2
  TRPL pb 13.4 nw 2 b 2 bw 0.6 lw 0.2 a -1.4
  TRPL pb 22.5 nw 2 b 2 bw 0.6 lw 0.2 a -4.5
  TRPL pb 24.3 nw 2 b 2 bw 0.6 lw 0.2 a -1.4
  TRPL pb 22.5 nw 2 b 2 bw 0.6 lw 0.2 a -1.4

LC no 102 titl 'Klasse 50 trans'
  TRAI type 'user' widt 3                 
  TRPL pw 3.3 nw 2 b 2 bw 0.6 lw 0.2        
  TRPL pw 3.3 nw 2 b 2 bw 0.6 lw 0.2 a -3.2 
  TRPL pw 3.3 nw 2 b 2 bw 0.6 lw 0.2 a -1.4 
  TRPL pw 5.6 nw 2 b 2 bw 0.6 lw 0.2 a -4.5 
  TRPL pw 6.1 nw 2 b 2 bw 0.6 lw 0.2 a -1.4 
  TRPL pw 5.6 nw 2 b 2 bw 0.6 lw 0.2 a -1.4

Several LC can be assigned to one action, and each action can only be assigned one favorable and unfavorable loadfactor per loadcombination - that is my understanding.
Would be interesting to know how ELLA handles this?
@SabineF do you have any info?

So in short, if you have different loadfactors on vertical and horizontal, you have to split them into different load cases.
