• Click the OK button to complete this pushover case definition. 14. Click the OK button to exit the Define Static pushover Cases dialog box. 15. Click the Save Model button on the main toolbar. This completes the definition of static pushover cases. SAP2000 Web Tutorial 1 104
Step 5: Running the Pushover Analysis 1. On the Analyze menu select Run Static Pushover. Note: To run a pushover analysis, you must first have pushover hinges and pushover load cases defined, at least a static analysis run, and, if steel members with Auto sections, or concrete members whose reinforcing is to be designed by the program are included, you must have run the design portion of the program. 2. A window is opened in which various phases of analysis are progressively reported. When the analysis is complete the screen will display as shown in Figure D-4. Note: Most of the information in the scrolling analysis window is appended to the *.log file that was created when the original analysis was run. Figure D-4: Screen Message When Pushover Analysis Is Complete 3. Use the scroll bar to review the analysis messages and check for any error or warning messages (there should be none). Note: One of the items you will see in the scrolling window is labeled Analysis Complete. As each pushover load case is running you will see the value continually changing. It is a measure of what percent of your force or displacement goal you have reached. When the Analysis Complete reaches 1, you have reached your goal. Note that the analysis may not to reach its goal (i.e., an Analysis complete of 1) because the structure catastropically fails earlier or because of numerical sensitivities. 4. Click the OK button in the Analysis window to close it. This completes running the pushover analysis. SAP2000 Web Tutorial 1 105
