  27. Earthquake • <5km from San Andreas fault • Seismic Zone: Z=4 • Occupancy Category: 4 • Importance Factor: I=1 • Seismic Source Type: A • ETABS Spectrum function for UBC 97 • Soil • Soil Bearing Capacity: 3500 psf • Soil Type: Sd • Soft Soil Profile • Liquefaction: YES • Wind • 70 mph wind speed • Exposure: B • Interstory Drift: 1” (UBC) Loading Pacific Team AEC Project 2008

  28. Wave - Steel Pacific Team AEC Project 2008

  29. Composite Floor (3” Steel Deck, 3” Concrete Cover) Shear Connections Wave - Steel Strip Footing Structural System & Load Path Cantilever beams (W24x146) EBF in both direction (HSS8x8x1/8) Columns (W14x162) Pacific Team AEC Project 2008

  30. EBF Bays Wave - Steel Sloped Floors Rationale for choosing EBF over MRF: 1- Lower costs 2- Better lateral resisting performance Braces & Sloped Floors High possibility of torsion  Put more braces in exterior bays. Pacific Team AEC Project 2008

  36. Rationale for choosing shear walls in both directions: 1- High performance 2- Savings in the overall amount of concrete due to reduced sizes of other elements (beams and columns) Two-way concrete slab Wave - Concrete Columns Load Path Strip Footing Pacific Team AEC Project 2008

  47. 30’ Hi-Tech - Concrete Some beams failed when designed with mild steel; so we decided to prestress those beams. 16’4” 13’8” Columns & Shear Walls 1st fl. Prestressed Beams (in all stories) 40’ 18’6” 19’ 22’5” 40’ Pacific Team AEC Project 2008

  50. We chose strip footing for all options to decrease concrete usage. (low risk of liquefaction, relatively good soil, relatively low axial forces in columns) Foundation Beams (Dimensions in mm) Pacific Team AEC Project 2008
