I have a model from a client to review. There are these horizontal members that are having the P-M Ratio value as greater than 1. Showing that the members are over stressed. Now the client asked me to ignore it, as these elements will be braced by the sag-rods but that they cant be modeled on SAP2000. Is it true that we can't model sag-rods on SAP? If yes, then how can I check that whether these sag-rods will reduce the P-M Ratio of these elements to 1 or not?
