Can robot generate all possible load arrangements

Hello

 

Does the robot strcutrual analysis makes for me all possible load arrangements, factored and unfactored

 

for eample if i have 2 spans beam i would have the following arrangements or cases:

 

Case 1 ) span 1 : factored load, span 2: factored load

Case 2) span 1 : unfactored load, span2: factored load

case 3) span1 : factored load, span2: unfactored load

 

let's say i have 4 span beam and i would like to draw BMD for all possible load cases

Example for 3 spans

(live load cases correspond to each span load) ;  crucial is to set each LL case in separate Group.

thank you for replying

may I know the steps to generate that

 

I tried going to Loads>>Automatic combinations>>Manual combinations>> next, and i selected the cases that i need as shown 

 

but the program will generate for the first combination all spans are factored ( 1.4DL + 1.6LL) which is fine

but for the second combination all the spans will have the following load (1DL), that's not excatly what I am looking for, I need the second combination to be for example first span (1DL) and second span (1.4DL + 1.6LL) as the BS 8810 code.

Hi

Do I have to create 3 cases with DL and 3 caes with LL?

for example

DL1 : load on span 1

DL2 : load only on span 2

LL1: load only on span 1

I created my load cases each on every span and created automatic load combination

but nothing happened

maybe I am doing it wrong

Have you run calculations?
