Steel Tub Girder Bridge Design Reports

Access the Steel Tub Girder Training Example

Follow the steps below to open the Steel Tub Girder Training Example.

1. Log in to your account and locate Project in the top-right corner.

   
2. Click Project, then click NEW in the top-left corner.

   
3. Under Example Project, click New Project within Steel Tub-Girder Training Example.

   

   
4. Provide a name for your project and open the example.

   

   

The initial download of the library components takes approximately 2 minutes 30 seconds. Subsequent openings of the same project are noticeably faster because OpenBrIM library objects are cached in your browser; loading then takes less than 2–3 seconds.

Follow the steps below to run the steel tub-girder code-check reports.

The Steel Tub-Girder Workflow supports the following code-check reports:

• Steel Tub-Girder Code Check

• Internal Cross-Frame Code Check

• Field Splice Code Check

• Pier Cap Code Check

• Pier Column Code Check

• Pier Footing Code Check

• Pile Capacity Code Check

1. Make sure the FEM button in the top-middle of the screen is active — the Analysis button only appears when FEM is on.

   

   The Analysis button typically takes around 15–20 seconds to appear.

2. When the Analysis button appears in the top-left, the FE model has been compiled and is ready to run.

   

   
3. Click Analysis to run the finite element analysis of the steel tub-girder bridge.

   

   Analysis for this project typically takes around 3.5 minutes to complete.

4. When the analysis finishes, click Close to exit the analysis interface.

   
5. Click Design to compute the parametric design parameters and collect the analysis results needed for the reports. Track progress in the top-middle of the screen during the design run.

   Keep the design tab visible until the run finishes — hiding or minimizing the page pauses result collection.

   

   

   The design run for this project generally takes approximately 9 minutes to complete.

6. When the design run finishes, click OK to start viewing the reports.

   
7. Click Report and Detailed Report in succession to display the available reports.

   
8. Detailed Report opens a range of design outputs — quantity reports, camber diagrams, superstructure analysis at 10-foot intervals, code-check reports for individual members, and load-rating reports.

   

The common steps before investigating individual design reports are now complete.

2. Click the Detailed Report icon to open the detailed report.

   

See Quick Tips — Exploring Design Variables in Depth below.

Pier Cap Code Check Report

Follow the steps below to access the pier-cap code-check reports.

1. The summary report runs pier-cap code checks against the AASHTO design template (marked in red).

   
2. Click the Detailed Report icon (marked in red) for AASHTO checks (flexure, shear, torsion, fatigue, reinforcement limits).

   

See Quick Tips — Exploring Design Variables in Depth below.

Pier Column Code Check Report

Follow the steps below to access the pier-column code-check reports.

1. The summary report shows pier-column results as D/C ratios or Pass/Fail.

   
2. Click the Detailed Report icon to open the detailed report (axial-moment interaction, axial compression, shear, torsion, reinforcement limits).

   

See Quick Tips — Exploring Design Variables in Depth below.

Pier Footing Code Check Report

Follow the steps below to access the pier-footing code-check reports.

1. The summary report shows D/C values and Pass/Fail status for flexure, one-way shear, two-way shear, and reinforcement limits.

   
2. Click the Detailed Report icon to open the detailed pier-footing code-check report.

Quick Tips: Exploring Design Variables in Depth

Tip 1 — Search by keyword

To quickly find a specific design parameter, press CTRL+F and type the keyword.

Tip 2 — Inspect any design parameter

To understand a parameter's annotation, computation, and underlying formula:

i) Hover over the parameter to see its annotation and additional details.

ii) Click the parameter to reveal the formula or expression behind it.

iii) The detailed report itself usually includes the computation and inputs in the surrounding narrative.
