AXIAL LOAD DUE TO GRAVITY LOAD NOT LATERAL LOAD

Dear all

 

Greetings.

 

I have model here contains of the main frame "rafter +column" (for gravity load +lateral load) + the lateral system (strut pipe +x bracing).

my question is :-----design output shows the highlighted member fail due to gravity load(dead +roof live load) not due to the  lateral load as it suppose , is there any way to let the program to analysis the model by applying the lateral load “wind " on the highlighted member then the load will transfer to the bracing .

 

In other way can i let the program to ignore the axial load from gravity load..

 

 

Is my load path assumption as described above is correct?

 

 

Note : i believe the members fail from the local deflection that occurred because of the gravity load ( is that correct ? 

 

 

Thanks. 3005.3D.std
