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