How much percentage variation we can allow between the WNC case and the Sustain Case?
As per my knowledge , once the rod removed , stiffness of the Whole system will get disturbed and there is some increase in load . that new load is called actual cold load. there is some degree of variation between the two( this because of 12.5% of material increase per feet). By value , it should be between theoretical cold load and the operating load....

correct me if i wrong
