1. West Point Bridge Designer Capstone Course Orientation

2. West Point Bridge Designer Purpose of this orientation 1. Create a guide for WPB 2. Introduce basic design functions in WPBdesign functions 3. Define structural members of Truss Bridgestructural members 4. Define test measurements and applicationstest measurements applications 5. Procedure for creating a template for practicecreating a template 6. Steps for design and testing of bridgedesign and testing

3. Designing a Bridge

4. Contest information if entering local contest

5. Deck and Support

6. Deck Material and Truck Loading

7. Truss Template (optional)

8. Title Block

9. Design Steel Truss

10. General Look

11. Component Parts of a Truss Bridge 3 Dimensional ViewElevation (Side) View

12. Load Test Animation After designing a bridge click the test icon under ‘Report’ menu. The design will animate and test the integrity of the bridge.

13. Oops The main support beam (red) was not strong or thick enough. The truss beam was not supported and collapsed. Areas that are under lots of stress turn red.

14. Load Combinations Load Combinations factor several different types of load at the same time IE A bridge must carry its own weight at the same time carry traffic and pedestrians It might also have special considerations for wind, snow, ice and sometimes earthquakes All Testing Total Load = 1.25Ws + 1.5Ww + 1.75T (1+ DLA)

15. Determining Engineering Properties Materials – Yield Stress-Modulus of elasticity -Mass Density Cross Section – Cross-section area- moment of inertia Graph – Strength v. length for Tension and compression

16. Follow this design tree To check for organization

17. Creating a New Bridge

18. Begin creating your design. This page describes the process of creating a bridge.

19. Step 2 Select no unless otherwise given instructions by your teacher and click next.

20. Step 3 Choose the design for your bridge. Keep in mind the weight and cost.

21. Completing a Bridge Follow the steps in the program Assessments- See assessments loaded to this lesson Test the bridge using engineering design propertiesengineering design properties
