Analysis
You have now defined all the load cases for which the frames will be analyzed. To start the analysis and display the Analyze dialog box:
The Analyze dialog box displays all the load cases available for analysis. Those load cases which are preceded by a green dot are available to be analyzed. A red light means that something is preventing that load case from being analyzed (e.g. no diaphragm or diaphragm masses are defined). In this example all load cases should be available.
The analysis will commence and a status message box will keep you informed of the progress. Upon completion of the analysis, click [OK] and notice that the status indicator light on the status bar turns green (if the self weight reactions of beams and columns are not current then he light will be yellow - see the RAM Manager documentation for a complete explanation on status lights). This indicates that the structure has now been analyzed for each of the load cases selected, and analysis results can be viewed for each load case separately.
If there is a stability problem with your model it will result in a warning during the analysis. Adjusting the member fixity can usually correct a stability problem. If there is too little stiffness in your structure, and the analysis is being performed with the P-Delta consideration, that might result in an excess P-Delta warning. You will see a message about the springs taking some of the lateral load. To see the report select Reports-Spring Forces.
The results of the analysis of each load case can now be viewed either on-screen or in printed reports. In either case you can select the load case(s) for which you want results displayed. If you have analyzed many load cases you may find your reports to be quite lengthy. The Reports - Select Cases command acts as an "Output Filter", allowing you to select which load cases will appear in the output.
