VisualAnalysis Advanced Tutorials: Spreadsheet Results

Project Description:

The purpose of this tutorial is to demonstrate the use of the built in spreadsheet in the Report View. The spreadsheet report will help in the advanced post-processing of plate elements. A list of spreadsheet functions will also be referenced at the end of this tutorial.

Modeling the Structure

Create a new Plane Frame. Create a 10 x 10 1ft square plate mesh. Make the plates 8 inches thick and 3000psi concrete. Pin the bottom nodes of the plate and your model should look like the picture below.


Loading the Structure

Apply 10- 5 K nodal loads in the positive X direction, under the "Wind +X loads" Load case. Your model should look similar to the figure below:

Now, the model is ready to be analyzed.

Analysis and Results

First check your model for errors and analyze the structure. Make sure to check the Load Case Manager to make sure "W +X" loads are included in analysis. You can click "Yes" for Analyze? under Service Cases in the Load Case Manager or select "Deflection Checks" for Load Combinations. For this project, we don't need any Building Code Combinations. After analysis, select the "W +X" load case in the Status Bar. You will see the deflected shape of the wall of plates.

Now, let's find the average stress across the middle of the Wall or at y = 5'. Select the plates just below the y = 5'. You will want to record the names of the Nodes that lie along the top line of the selected plates. For this particular model, they are: 12, 11, 28, 39, 50, 61, 72, 83, 94, 105, and 116. Your model should look similar to the figure below:

Right | Click and select "Report Selected Plate". In the Report view, use the Report | Report Properties command and change the Report Properties to report the Plate Global Stresses and Nodal Reactions.

Click on the Spreadsheet View check box in the Modify Tab while in the Report Viewer. Report spreadsheets can be copied and pasted into Excel spreadsheets for data extraction and manipulation. Your report spreadsheet should look similar to the figure below:

Data extraction and manipulation can also be performed in VisualAnalysis. The data in the grey cells of the spreadsheet can not be edited however calculations may be performed in the white cells. Below, the "VLOOKUP" function has been used to look up the Sigma X stresses at the previously recorded nodes and averaged them using an "AVG" function.
