Hello, we designed a steel floor on reinforced concrete columns in the attached project. However, we gave up on the reinforced concrete floor, we modeled the reinforced concrete floor as the ground floor and the steel floor as the 1st floor in the program. We cannot delete the ground floor from the floor general settings in the program. When you say copy the 1st floor by deleting the ground floor from the ground floor, something absurd happens. My question will be, can we do the analysis by deleting the reinforced concrete of the ground floor and leaving the steel floor on the 1st floor. Also, when you look at DESIGN on the foundation anchors, it says the anchor type is wrong. This may be the cause. (I request comments for other noticeable errors.) I wish everyone a good work.
