In SAP2000 v14, Would I be able to disable the AISC Code design check after running load cases? if so, How? and would I be able to define my own design limits (For example, yield stress) for certain members?
I don't understand your issue regarding disabling the AISC design check.. because you have to run a separate design check after the analysis in order to obtain design code results. If you just run the analysis by itself there will be no design check. If you run an analysis, results from your load combos will be available as you defined them. "Stress" results will not be available with frame elements using analysis only.. stress will be reported only for area and solid elements
