Hello, I would appreciate some help regarding the application of self-weight in SAP2000.
So I am modeling a cable net, I want to 'calibrate' it in two steps; one for the Load Case DEAD and the second one for Load Case TARGET (for the prestressing cable forces) continued from the Dead Case. (NONLINEAR)
My question is: should I consider self-weight in the TARGET Load Case too? Because when taking the stiffness matrix from the DEAD Case (Nonlinear), it's like its counted already?
Can someone shed a light on this?
I can either implement self-weight adding the load pattern Dead into the Target Load case, or adding the self-weight multiplier in the Target pattern (so it will be together with the Target forces implemented), but I don't know if its needed. It usually takes more computational time if I take it into account.
Thank you
