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
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

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

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
