Click primary

Define Load 1 with loading type Dead Load

And title as DL

Define Load 2 with loading type Live Load

And Title as LL

Go to Dead load and add member load

Click uniform force

and direction as GY and apply it to the rafter.

and add remaining member loads in dead load and apply it as given in the question.

Add member loads in Live Load as given in the question and apply it to respective members.

Click on the Combination load case under the loading option and name it as 1.5DL +1.5LL and put load factor as 1.5 for DL and 1.5 for LL.

2.

Go to analysis in ribbon tool bar

define comand

tick all and click add

Result 1 :

The maximum moment in the secondary beam for 1.5DL +1.5LL case is in beam no 75

Bending moment value is M@Z = 53.163 KN-m

go to beam results and click load as combined 1.5DL +1.5LL

Range as group inclined bracing and then ok .

Result 2 :

3.

Go to thegiven attachment

open the model and click on analysis and then click on run analysis option

see the warning in view option

see the instability in the result layout option

Lz as a default use for apply to member

Ky as a factor take it as 1.2 as per IS 800

Kz as a factor , take it as 1.2 as per IS 800

Take utility ratio as 1.2 and apply to the structure.
