  2. Project Goal • Multi-disciplinary, collaborative teamwork in a building project • Apply discipline knowledge and technologies. • Knowledge management. Requirements • The year is 2015 • A 3-story building • Total fund, $5,500,000 • Maintain the footprint of the existing buildings • A collection of rare cactus varieties about 16,000 square feet is protected by the “Society Environmental Desert Studies.”

  3. Site Map The site map of new engineering school • Location • Express University is located in Phoenix, Arizona. • Climate/Weather • Annual average temperature is 61F. • Annual rainfall is 7.6 inch The campus map of Express University

  4. Analysis of Context • Good use of materials • Insulation Concerns • Aesthetic taste to enrich environment The site map of new engineering school

  5. Analysis of Landscape • Cactus, a typical plant in a desert environment • A collection of rare cactus varieties between two footprints • Other green plants on campus The site map of new engineering school

  6. Analysis of Circulation Main roads Subdivided roads Outside public space A collection of cactus Entrance to each footprint

  7. Design Concept static dynamic

  8. Design I Concept conversation The silent conversation between desert and architecture • static status • regular geometric forms • solid exterior look • symmetrical layout static

  9. The first layer of lines is along the footprint. 1 Design I Analysis The second layer of lines reveals the horizontal lines along X, Y axis. 2 The third layer of lines displays the relationship between horizontal and vertical lines. 3 Vertical circulation of the building The relationship of three layers of lines along X, Y, Z axis 1 2 3

  14. Gravity Loads

  15. Gravity Loads Gravity load path ——Steel Braced frames Gravity load path ——Two way slabs

  16. Lateral Loads Wind Zone Map

  17. Lateral Loads Lateral load path —— Braced frames Lateral load path —— Concrete MRF

  18. DesignGoals “Simplicity and functionality through early collaboration and exchange of ideas, inspirations and constraints.” • Simple • Regular • Least intrusive structural system • Constructability • Lower budget

  19. Option 1 -- Framing Laterally Braced Frame • 2VLI20 composite deck with 2.5” light weight concrete slab • Beam & Girder: full composite with slab • 6”x6” HSS shape braces • Column size: W14x68 • 10” concrete walls Framing Plan

  20. Structural Options Option 2: Option 1: • Concrete frame • One-way slab • Waffle slab in auditorium • Composite floor system • Laterally braced frame • Cast-in-place concrete walls in elevator shaft • Spread footings

  21. Option 1 First floor Third floor Second floor Matching The Architectural Plan

  22. Option 1 -- Sizes W21x48 Typical Sizes: 10” wall 2VLI20, 2.5” W18x119 W21x48 W16x40

  23. Option 1 -- Foundation Foundation Plan: • Shallow foundation • Spread footing under columns, with size of 8’x8’ • Strip footing under concrete walls, with a width of 4’ Foundation Plan

  24. Option 1 -- Connection Beam-Girder Typical connections Girder-Column flange Girder-Column web Beam Splice

  25. Option 2 -- Framing Framing Plan——Concrete Frame: 1st Floor Framing Plan 2nd and 3rd Floor Framing Plan

  26. Option 2 -- Sizes • Columns • 18” x 18” • 6#7 bars • #3@14” Ties Typical Element Sizes: • One way slab • Depth: 7” • Steel: #3@6” • Beams • 14” x 21.5” • 6#7 bars • #3@10” Ties Column Section Beam Section
