The template structures available using the 3D Frame form include an open frame building, perimeter frame building, beam-slab building, or flat plate building.
Choose the type of frame by clicking on it in the 3D Frames Type drop-down list in the upper left corner of the form. A drawing of the selected frame type will be shown in the small display box.
Open Frame Building or Perimeter Frame Building
Open Frame/Perimeter Frame Building Dimensions
Number of Stories edit box. Specify the number of stories for the structure in this edit box.

Use Custom Grid Spacing and Locate Origin check box and Edit Grid button. When this check box is checked and the Edit Grid button is clicked, the Define Grid System Data form displays. Use the form to specify the grid spacing and to locate the origin as needed.
Section Properties
Beams and Columns drop-down lists. SAP2000 will suggest section properties for the beams and columns in these drop-down lists. The section properties will apply to the entire length of the beams and columns.
TIP: Click the + (plus) symbol next to the drop-down lists to access the Frame Properties form; use that form to add, modify or delete a frame section definition. The Assign menu > Frame > Frame Sections command can be used to change the section property later, if needed.
Restraints check box. When this check box is checked, SAP2000 will assign default restraints to each point at the base of the model.
Example: Use of the Open Frame Building option is demonstrated in Problem O and Problem Z.
