  1. Sustainable Roof SystemsTHE PLANETEERS In collaboration with LionForce Systems Dr. Diana Glawe Professor Kimberly Drennan

  2. LionForce Systems • Panelized Pre-Fabricated Houses • Goals: • 1. Create structural support and environmental seal • 2. Increase 14-ft roof span  20 ft • 3. Increase 2-ft overhang  4 ft

  3. Roof-to-wall Joint & Span Notice the air gap!

  4. Overhang

  5. Design Overview

  6. Pro Engineer Drawings

  7. Simulation with Pro Mechanica

  8. Wedge Critical Load

  9. Load Calculations

  10. Load Calculations • Code: L ~ 30 psf • For: 6 in. thickness, 20 ft. span, 2 ft. overhang, 8:12 pitch • Max stress: 177 psi • Yield stress: 25 to 200 ksi

  11. Overhang Recommendations Overhang with Truss Support

  12. Overhang FBDs Internal FBD for member AC External FBD of Overhang Support Bracket

  13. Thermal Considerations http://www.transconsteel.com/products/ultraframe/stud.asp

  14. Thermal Considerations

  15. Fit Tests Mechanical Fit tests – ABT wall panel, Transcon Roof panel

  16. Evaluation of Objectives LionForce goals v. our success • Structural support & environmental seal in wall joint • Success! • Increase span • Success! • Increase overhang • Partial success
