How can I efficiently remove one cable at a time in a network arch bridge model with 48 cables, without saving each cable removal as a separate file? Also, is there a way to combine the envelope results of the 48 cable removal load cases with the results at the end of construction?

Answer:

These situations needs to be modeled individually in different files, and in construction stage. There is an option for independent and accumulative results in construction stage. However, this will not be helpful for this type of checking. Going by standard practice:
1) Cable has to be deactivated
2) 1.5 times the cable force has to be applied in the direction of cable pretension (To model sudden break. Ignore, if the loss of cable force is controlled)
3) Activate the cable element again and re-stress
For this process, all the files would have to be generated separately.
The envelop of these load cases would have to be done in excel.
