Start of Tutorial
- Select to open the Open dialog. Locate the file Tutor2.csl and then click Open.
- Click the Materials tab to activate the Materials screen, as shown in Figure 2. As indicated in the Problem Data, limit the maximum number of strands that may be debonded per row to 50% and the maximum total number of strands that may be debonded to 50%. Under Maximum Auto Debonding Percentage, enter 50 in the Per Row% field and 50 in the Total% field.
- Click the Analysis Tab and click Run Analysis. It is required to run an analysis before proceeding to the Beam tab. If at any point during the process information is incomplete a warning will appear. The program will not allow selection of the Beam tab until an analysis has ben performed.
- Click the Beam tab, select beam 2 from the Beam list , and click Strand Pattern to activate the Strand Pattern, as shown in Figure 3. Since a straight pattern was selected on the Materials tab, only straight strands are available in the Type list.
-
Click Auto Design and the program will automatically generate a straight strand pattern using 16 strands, as shown in Figure 4.
The strand pattern (or debonding pattern) that is automatically generated is optimized. It contains the minimum number of strands that is necessary. (For more information on the algorithms used for automatic generation, see Automatic Straight Strand Pattern Generation and Automatic Straight Strand Pattern Generation.)
You can manually input a pattern, or modify an existing strand pattern that was automatically generated. To edit an existing pattern, highlight it in the list, make the necessary changes and click Modify. It is not part of this tutorial to modify the pattern.
- Click Debond and the Debonding Pattern will display, as shown in Figure 5. You can have the program automatically calculated the debonding/shielding information by clicking Auto Debond; however, for this tutorial, since no debonding is required, all debonding lengths remain as zero after clicking the Auto Debond. Click OK, or Cancel, and return to the Strand Pattern. Click OK again to return to the Beam.
- Precast/Prestressed Girder allows you to use either metric or U.S. units and switch back and forth at any time. For this tutorial, use metric units. To switch to metric units, select the Project tab and select S.I. Units (Metric).
- Select the Analysis tab and click Run Analysis to run the analysis again. Now, go to the Beam screen, select 2 from the Beam list, and click Strand Pattern to activate the Strand Pattern. Notice that the strand pattern has been retained. Click OK to close this screen and return to the Beam screen.
- Select Print from the File menu to print the project results. Select the appropriate options and click OK. Following this tutorial is a printout of the output for Tutorial 2.
