Results

You may work with the results of a solution by viewing and sorting data in the spreadsheets, graphically plotting them with the model or by viewing detailed beam reports. You may also print the results in any of these forms. To learn about printing results, see Printing.

Upon the completion of a static solution, RISA opens the Results Toolbar and the Design Results Spreadsheet, and plots all the design shapes to the screen. If any warnings have been written to the Warning Log, it is displayed as well. You may then proceed to view any results and make any changes for further analysis.

If you make any changes to the model that would void the results, such as moving points or adding beams, the results will be purged and another solution will be required before the results can be viewed again.

Each of the result types is described in it’s own section:

Results Spreadsheets

• Hot Rolled Design Results
• Cold Formed Design Results
• Wood Design Results
• Concrete Beam Design Results
• Steel Products Design Results
• Wood Products Design Results
• Deflection Results
• Vibration Results
• Beam End Reaction Results
• Wall Results
• Material Take-Off

Detail Reports

• Concrete Beam Detail Reports
• Concrete Column Detail Reports
• Beam Detail Reports

Saving Results

When you save a file that has been solved you may also save the results. The next time that the file is opened the saved results will be opened as well. You may use the Application Settings on the Tools Menu to change the way that you are prompted to save results.

If changes are made to the model, any saved results are deleted. Saved results for models that no longer exist in the same directory are also deleted.

Results Spreadsheets

You may access the result spreadsheets by selecting them from the Results Menu.

Choosing a Floor for Results

• The Floor of the results you are viewing is listed in the title of the spreadsheet. To change to another Floor select it from the drop down list on the toolbar.

Finding Results

• To go to a certain item while in a spreadsheet click the Find  button, and type in the desired beam or point label.

Excluding Results

There are two ways to exclude results so that you can work with the results that are important to you.

Excluding Results After the Solution

You may run the solution and then graphically select the nodes, members, wall panels, slabs, and design strips that are of interest. By clicking the  button, the spreadsheets and printed reports will be updated so that they will only have results for the selected items. All of the spreadsheets and reports will be controlled by this selection and you may adjust this selection at any time.

Excluding Results While in Spreadsheets

You may also select the results of interest on each spreadsheet. While viewing spreadsheet results you may select the last line of interest and exclude the rest. Exclusions are applied independently for each results spreadsheet. Any exclusion applied to the Member Forces spreadsheet will not affect the Member Stresses spreadsheet, etc. Excluding items graphically will reset all of the spreadsheets to match the graphic selection. If you wish to combine these two features to fine tune the results perform the graphic selection first.

To exclude results click on the last line of results you wish to keep and then right click and select click the Exclude After. You can bring the results back by right clicking in the spreadsheet and selecting Unexclude.

Note

• It might be best to first sort the results before excluding. As an example, let's say that you only wanted to view members with Code checks greater than or equal to 0.7. To do this you would open the Steel Code Checks spreadsheet and sort the members by Code Check magnitude. Then you would visually identify the last member with a Code Check of 0.7 and use the Exclude feature to exclude all members after that one.

Graphic Results

Most of the analysis results may be viewed graphically as well as in the spreadsheets. For the beams you may plot and color-code the members by bending, shear or deflection checks. See Model Display Options for more information.

To Plot Results Graphically

1. If you do not already have the model view open click the New View  button on the RISA Toolbar.
2. Click the Model Display Options  button on the Window Toolbar.
3. Select the options you would like to view and click Apply.

Clearing Results

You will be provided with a warning if changes are made to the model that might invalidate the current results. Should you decide to proceed, the results will automatically be cleared and you will have to re-solve the model to get results once you are finished making changes. This warning may be disabled in the Application Settings on the Tools Menu.

To manually clear results, click the Clear Results  button.

Opening a model with a solution file that was saved in a different version will also prompt you to delete the solution file in order to open the model.

Member Detail Report

After you have performed a solution you may view a detailed report of the beam design results. This report contains detailed loading, force, and deflection diagrams for the beam members. Use the  button to switch the diagram plots from Load Categories to Load Combinations, and the drop down menu to select the desired category or combination. The report also contains detailed design information on the shear and moment capacities, member deflection, end reactions, composite properties, and floor vibration. Use the  button to see the detail report for the next or previous member.

To View a Detail Report

• To view a member detail report after running a solution, click on the    button on the Selection toolbar and then click on that member. If you do not already have the model view open click the New View    button on the RISA toolbar.
• You may also access the detail report while viewing a member results spreadsheet such as Design Results by clicking the    button on the Window toolbar.
• You may also use the Results  Members  Detail Report menu option to open the report for any member.
  • Once the detail report is open, select a Load Combination or Load Category    from the pull down list.
  • The detail report diagrams the load, force, and deflected state of the member. You can use the Options button to pick the details or diagrams that you wish to display or print.

Note:

• For sloped members, the load diagram will display the load applied in the local y-axis and the user applied loads will be in parenthesis.
• - This button will allow you to take a snapshot of the current detail report you are viewing so that it can be added to a report. View the Printing topic for more information.

The available diagrams provided are:

The load categories and load combinations that may be selected are outlined in the Loads sections of this manual. Refer to Loads - Load Types and Loads - Load Combinations for more information.

Note:

• The multiple colors shown in the diagrams represent live load reduction.
• To control whether the displayed diagrams and values consider LL Reduction, click on the button.

Interactive Diagrams

Once a beam detail report is open, you can also click on any of the shear, moment, deflection, or axial diagrams to open an interactive diagram. Use the cursor at the bottom to drag along the length of the member to see how the value changes.

Note:

• The multiple colors shown in the diagrams represent live load reduction. When the LL Reduction box is checked, the value displayed on the diagram will represent the reduced value. When the LL Reduction box is unchecked, the value on the diagram represents the unreduced value.

Concrete Member Detail Reports

Concrete member detail reports are similar in function to detail reports for other materials, but they are different in the type and amount of information they convey. One of the largest differences is that the force diagrams are always envelope force diagrams, because the majority of the concrete design results are based on the envelope forces.

The detail reports for concrete Beams and Columns are discussed in greater detail in the Concrete - Design Results section.
