Step 4: Defining Static Pushover Cases
For this tutorial example we will define six static pushover cases. The first will apply the gravity
load to the structure, and the other five will apply different distributions of lateral load to the
structure.
1. From the Define menu choose Static Pushover Cases…. This will display the Define Static
Pushover Cases dialog box.
2. Click the Add New Pushover button to display the Static Pushover Case Data dialog box.
3. In this dialog box:
• Type GRAV in the Pushover Case Name edit box.
• In the Options Area select the Push To Load Level Defined By Pattern option button.
Note: Typically the Push To Load Level Defined By Pattern option is used to apply
gravity load, and the Push To Displacement Of option is used to apply lateral
pushes.
• In the Load Pattern do the following:
ä Select DL from the Load drop-down box.
ä Type 1 in the Scale Factor edit box.
ä Click the Add button.
ä Select LL from the Load drop-down box.
ä Type 0.25 in the Scale Factor edit box.
ä Click the Add button.
• Accept all of the other default values. Note that the default Control Joint, joint 19, occurs
at the roof. The dialog box appears as shown in Figure D-3.
• Click the OK button to complete this pushover case definition.
Note: There are five control parameters in the right-hand side of the Options area.
These parameters are used to control the pushover analysis. For most analyses the
default values are sufficient.
The Minimum Saved Steps and Maximum Saved Steps provide control over the
number of points actually saved in the pushover analysis. The default values are
