  18. Michael A. Hebert Structural Option Spring 2006 Ann & Richard Barshinger Life Science & Philosophy Building Franklin & Marshall College – Lancaster, PA Breadth Topic – Architectural Impact Vierendeel Truss System

  19. Michael A. Hebert Structural Option Spring 2006 Ann & Richard Barshinger Life Science & Philosophy Building Franklin & Marshall College – Lancaster, PA Breadth Topic – Architectural Impact Long Span Steel Joists

  20. Michael A. Hebert Structural Option Spring 2006 Ann & Richard Barshinger Life Science & Philosophy Building Franklin & Marshall College – Lancaster, PA Breadth Topic – Mechanical Impact Partial HVAC Ductwork Plans First Floor Second Floor HVAC Duct Sizes

  21. Michael A. Hebert Structural Option Spring 2006 Ann & Richard Barshinger Life Science & Philosophy Building Franklin & Marshall College – Lancaster, PA Conclusions & Recommendations The lateral force resisting system can be safely reduced from 10 frames to 6 frames for a estimated savings of $18,000. A drilled pier foundation system is not a cost efficient replacement for the spread footing system. The Vierendeel truss is extremely effective and efficient for carrying significant loads over a large span.
