Parametric Bridge Engineering [QG-1]

→ Log in to your account and locate the 'Project' option in the top right corner.

→ Click on 'Project' and then select 'NEW' from the top left corner of the screen.

→ Under the 'Example Project' section, click on 'New Project' specifically located within the 'Steel I-Girder Training Example'.

→ Provide a name for your project and proceed to open the example project.

→ Click on the 'DATA' button located in the bottom-middle section of the screen.

This will open a spreadsheet.

→ Click on 'Plate Girder' under the 'Superstructure' section in the workflow tree.

This action will display all the project girders and their corresponding parameters in the spreadsheet.

→ Let's take a look at how the Finite Element model looks with the current web depth before changing it.

→ Click on the icon in the top left corner to open the sliding menu.

→ In the menu, you will see MODEL, FEA, CAD, DOCS, SUPPORT, and USER SETTINGS.

→ To activate the Finite Element model, click on FEA.

→ The Finite Element model appears as shown on the side with the current web depth (84 inches).

→ To modify the web depth parameter of the 'G4' girder, click on the corresponding 'Web Depth' cell of the girder in the spreadsheet.

→ Next, enter the value of 55 inches as the web depth in the cell.

→ The new Finite Element model appears as shown on the side with the updated web depth.

→ Open the sliding menu again by clicking on the icon in the top left corner, and then click on 'MODEL' to switch to the 3D view.

→ You can see the changes in both the 3D view and the Finite Element model in the visual on the side.

→ Click on 'Support Line' under 'Bridge Geometry' in the workflow to access the skew angle parameter.

→ To change the skew angle of 'Abut1', click on the corresponding cell (mark in red).

When the skew angle value of 'Abut1' is set to zero, it will appear as shown on the right-hand side.

When the skew angle of 'Abut1' is set to '-15' degrees, it will appear as shown on the right-hand side.

→ Click on the skew angle cell of 'Abut1'.

When you click on the cell, you will see three-dots appear to the right of the cell.

→ Then, click on the three-dots that appear on the right side of the cell.

→ From the options provided, select 'Copy Parameter'.

Now, the skew angle parameter (not the value) has been copied.

→ Expand the 'Cross Frames' section under 'Superstructure' in the workflow.

→ Then, click on 'Cross-frame K Top' to access its parameters.

After clicking on the skew angle cell of 'CFTK1', you will see three dots appear to the right of the cell.

→ Click on the three dots to access additional options and select 'Paste' from the menu.

→ Perform the paste operation for 'CFKT28' and 'CFKT29' in the same manner as before.

As observed, the skew angles of the cross-frames have now been aligned with the support line.

→ To align the roadway with the skew angle of the support line, expand the 'Superstructure Attachments' section in the workflow and click on 'Roadway' to access the parameters related to the roadway alignment.

→ Then, click on 'Edit' from the three-dot menu on the right side of the 'Roadway Dimensions' cell.

→ Paste the skew angle copied from 'Abut1' into the 'Skew' parameter at zero station.
