2. Introduction Background Design Objectives Material Selection Cost Evaluation Concept Design Product Evaluation Conclusion Recommendations Answer Questions

4. Russell Foundation Founded By Bishop Michael Russell and his Father In 2003 Faith Based Community Development Organization Renders Self-sufficiency Programs to Help Stabilize Families and Communities Provides Jobs for Local Communities Environmentally Friendly Initiatives

5. Reasons For Design Reduce Traffic Congestion around Chicago-Indiana Area Provide High Speed Transportation Create Jobs in Indiana Pioneering Environmentally Friendly Mass Transit Solutions

6. Preliminary Design

7. Customer Requirements Travel 75 MPH Support Renewable Energy Source Easy Assembly Easy Maintenance Smooth Rail Transition Appearance Support 160,000 lb load Minimize Stopping Time Minimize Cost Minimize Environmental Effects

8. Engineering Requirements Minimize Resistance (Rail) Maximize Allowable Stress (Structure) Equipment Hours Labor Hours Minimize Rail Height Difference Public Appearance Rating Maximize Allowable Stress (Rail) Maximize Allowable Stopping Force Minimize Cost Minimize Environmental Effects on Material

10. Column Support Box beam Concrete base Bolted to cross- support

11. Cross Support Box beam Bolted to column Supports rails

12. Standard I-Beam W27 x 368 Standard Size Internal height equal to 25.43 inches Fits standard 22 inch tire diameter

13. Column Support Assembly All parts bolted and welded

14. Full Assembly

16. Types of Steel Two common types used: ASTM A992 and ASTM 588 More common steel types reduce cost High strength, low alloy steel, which used recycled metals Saves on cost of manufacturing Environmentally friendly

17. Physical Properties ASTM A588ASTM A992 Contains Chromium for weather resistance Made using 95% recycled material Develops oxide coatingInexpensive 50 ksi yield strength

19. Structural Steel ASTM A-588ASTM A-992 Price per cwt from Nucor-Yamato Steel $51.10$46.60 Price per 80ft Beam $6483.85$5971.32 Price difference per section $512.53

20. Price Comparison Consider long term maintenance and repair cost Northwestern University experiment A992 corrodes 64% more over time than A588 A992 would last less than half as long as A588 (weathering steel)
