  4. Building Location • Michigan State University Campus Existing Building Agricultural Hall and Annex North Kedzie Hall www.msu.edu Agricultural Hall and Annex Ismail Al-Hadhrami-Structural Option

  5. Building Information • Designed to be five-story with penthouse • Three floors have been built • 1000 SQ FT/Floor • Use – office building Agricultural Hall and Annex Ismail Al-Hadhrami-Structural Option

  6. Structural Systems • Gravity System - Cast-in-place one-way joist - 30” and 20” clear spans - Joist depth = 16” deep + 4.5” slab - Girders depth = 27.5” + 4.5” slab • Columns - 24” x 24” Agricultural Hall and Annex Ismail Al-Hadhrami-Structural Option

  7. Structural System • Lateral System - Seismic Loads govern - Concrete Moment Frames Agricultural Hall and Annex Ismail Al-Hadhrami-Structural Option

  8. Proposal • Building Design Codes Comparison • US Standards vs. British Standards • Focus - Gravity Loads - Loads Combinations - Wind Design Procedures • Gravity Systems (US Standards) - Wide-Module One-way Joist System - Flat Slab - Composite Steel with Composite Deck - East Lansing, MI • Gravity Systems (British Systems) - Flat Slab - Two-way Slab with Interior Beams - Muscat, Oman • Lateral System - Concrete moment frames for concrete structures - Moment frames and braced frames for steel structure • Cost and Time Comparison Agricultural Hall and Annex Ismail Al-Hadhrami-Structural Option

  9. Design Codes • US - ACI 318-02 - IBC 2003 -ASCE 7-02 • British -BS 8110 -Reinforced Concrete Building Examples based on BS 8110 Agricultural Hall and Annex Ismail Al-Hadhrami-Structural Option
