Parametric Bridge Engineering [QG-1]

Access an Example Steel Bridge Model

Please follow the instructions below to access ‘Steel I-Girder Training Example’

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.

2

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

3

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

Please follow the instructions provided below to change girder web dimensions.

1	Click on 'DATA' located in the bottom-middle section of the screen. You will see that a spreadsheet opens. To adjust the height of the spreadsheet, you can click and hold the 'DATA' with the left mouse button, then drag it to the desired position. To close the spreadsheet, you just need to click once on the 'DATA' button.

3	Click on 'Plate Girder' under 'Superstructure' in the workflow. You will see all the girders and their parameters in the spreadsheet for the project.
4	To change the web depth parameter of the 'G4' girder, click on the 'Web Depth' cell of the girder. When you click on the cell, you will see three dots appear to the right of the cell.
5	Click on the three dots that appear on the right side of the cell. After that, click on 'Edit (Spreadsheet)'.
6	In the newly opened spreadsheet, we can define the 'Web Depth' parameter as station dependent. After the definition is done, click the 'Back' icon (marked in blue) to apply the changes to the project. You can also define other parameters of the girder as station dependent.

Please follow the instructions provided below to align the cross-frame skew with the support line's skew.

1	Click on 'DATA' located in the bottom-middle section of the screen. You will see that a spreadsheet opens. To adjust the height of the spreadsheet, you can click and hold the 'DATA' with the left mouse button, then drag it to the desired position. To close the spreadsheet, you just need to click once on the 'DATA' button.
2	Click on the 'Support Line' object in the workflow to set the skew angle.
3	When the skew angle value of 'Abut 1' is zero, it appears like this.
4	When the skew angle of 'Abut 1' changes, it appears like this. As seen, the cross-frames are not aligned according to the support line.
5	To align the skew angle of the cross-frame with the support line, click on the three dots to the right of the skew angle input cell of the support line. Then, click on 'Copy Parameter'. Now, the value of the skew angle has been copied parametrically. The parameter we copied exactly is: Abut1.s_skew Therefore, the copied value will also change whenever the skew angle of ‘Abut 1’ changes.
6	Go to the cross-frame objects where the skew angle will change. Click on the three dots to the right of the 'Skew Angle' input cell. (Instead, after clicking on the cell, you can also paste it using CTRL+V.)
7	You no longer need to manually change the skew angles of cross-frames every time the support line skew angle changes. The skew angle value of cross-frames will now be parametrically equal to the skew angle value of the support line.
