Step 8: Displaying Pushover and Capacity Spectrum Curves 1. From the Display menu select Show Static Pushover Curve... to display the Pushover Curve dialog box. Note: If this dialog box does not fully fit on your screen then you may want to increase the resolution of your screen. The dialog box should fully fit on the screen if your resolution is 800 x 600 with small fonts, or 1024 x 768 with large fonts. 2. If no plot is visible in the plot area, then click the Display button at the bottom of the form. Note: If at any time the plot area display is not visible in the Pushover curve dialog box, click the Display button. 3. For practice, press the F1 key on the keyboard to see context sensitive on-line help pertaining to this dialog box. 4. When finished with the online help click the “X” in the upper right-hand corner of the Help window to close it, or choose Exit from the File menu on the Help window. 5. Notice that in the Plot Type area, the Base Shear vs Control Displacement option is selected. Note: The base shear that is plotted in the Base Shear vs Control Displacement plot is the resultant base shear. The displacement plotted is the displacement in the control direction (not resultant) at the control joint. 6. The dialog box currently appears as shown in Figure D-7. Note the following: • The Demand Spectrum area and the Damping Parameters area are gray and inactive. These areas will become active when the Capacity Spectrum option is chosen in the Plot Type area. • There are four boxes just below the plot area. These boxes are the Cursor Location, the Performance Point (V, D), the Performance Point (Sa, Sd), the Performance Point (Teff, βeff). When the Base Shear vs Control Displacement option is chosen in the Plot Type area, only the Cursor Location box is active. Place the cursor (mouse pointer) anywhere over the plot and the coordinates of the pointer will appear in the Cursor Location box. The Performance Point boxes are only filled in when the Capacity Spectrum option is chosen in the Plot Type area. • If we wanted to include some notes with any printed graphic output, we could type those notes in the Additional Notes For printed Output edit box.

Figure D-7: Pushover Curve For Pushover Load Case PUSH2 7. Suppose we want to change the color of the base shear versus displacement curve from the default green color to blue. To do this click on the green color box in the Plot Type area to open the Color dialog box. 8. In this dialog box: • Click on one of the blue colored boxes. • Click the OK button to change the color. • If necessary, click the Display button to redisplay the plot. 9. To change the curve color back to the default green, click the Reset Default Colors button. 10. Now we will override the axis labels and range. The axis labels and range will appear on the screen and on any graphic output. Click the Override Axis Labels/Range button. The Override Axis Labels and Range dialog box appears.
