Finite Elements - Frame Element (4.5.2.1)
Beams and columns are automatically modeled as frame (bar) finite elements.
All 6 degrees of freedom are considered at the joints of columns and beams.
If slabs are modeled as rigid diaphragms, those that correspond to rigid motion of these degrees of freedom are removed.
Reinforced concrete and steel columns and beams are automatically modeled and analyzed by using a frame model in accordance with the finite element method with 6 degrees of freedom .
Rigid, Semi-Rigid, and Flexible Diaphragm Types
If the full rigid diaphragm in the slabs is accepted as Rigid, Semi-Rigid, and Flexible Diaphragm Types , the degrees of freedom required for rigid behavior are automatically removed.
