This tutorial provides the basic steps of performing a frame analysis using SAP 2000. It is based on the design project example shown below, the complete solution of which is provided as a handout ...

Analysis Steps:

• Generate the frame geometry from analysis templates
• Set Boundary Conditions
• Define and assign frame sections
• Define static load cases
• Assign member and joint loads for each load case
• Define load combinations
• Run Analysis
• Print Output Tables

The default boundary condition in the template is simple supports at the bottom. We need to change those to fixed supports. After selecting these joints, one can either use the menu: Assign > Joint > Restraints, or the quick menu button at the top (Restraints is the first one)

After the member sections are defined, select members with common sections and assign the respective section from menu: Assign > Frame > Sections. After assigning the sections, 2D/3D Extruded shape of the members can be seen from Menu: View > Set Elements > Extruded shape or using the shortcut menu button .

Define the type of load cases considered in design. Dead load (DL), live load (LL), and earthquake loading (E) are considered in this example. New load cases can be added from the below menu item.
