  10. Structural Requirements • Design wind speed: V33 = 80mph • NBCC • (National Building Code of Canada) • Most severe case: North wind • Wind parallel to corridor • Design snow load: • Uniformly distributed load • 25psf W a v e 2 0 0 1

  11. Final Structural Solution Beam : W18X35 Girder: W24X76 Column: W14X48 • Steel Moment resisting frame • 3” 20GA full composite slab • 12m girder, column/column span W a v e 2 0 0 1

  12. Foundation Design • Spread footings :1.5m X 1.5m X 60cm • Grade beams: 30 cm X 60cm W a v e 2 0 0 1

  13. Architectural/Structural Integration Column!! • No structure element intrusion in architectural space in 1st and 2nd floor • One column intruded flexible offices are, but acceptable to architect W a v e 2 0 0 1

  14. Architectural/Structural Integration W a v e 2 0 0 1

  15. Final Roof Design: Structure N • Conventional Truss: Double angles • Truss Spacing: 20’ oc • Purlin Spacing: 5’oc EW, 7oc NS • Simple connections to main structure W a v e 2 0 0 1

  16. Roof Design: Truss Configuration N WIND L 2X2 ½ X 5/16 L 2X2 ½ X 3/16 • Sloping N-S direction • Suction effect due to North wind at wing trusses—uplifting • Compression on end trusses WIND L 2X2 ½ X 3/16 W a v e 2 0 0 1

  17. Roof Design: Truss Configuration con’t N WIND L 2X2 ½ X 3/16 • Sloping E-W direction • Wind parallel to ridge suction effect • Uplifting at connections L 2X2 ½ X 3/16 L 2X2 ½ X 3/16 W a v e 2 0 0 1

  18. Roof Design: Truss Configuration con’t • Purlin size: C 9X20 • 1 ½” steel deck • Expanded perlite and fibers impregnated with integral asphalt waterproofing • 2hr fire rating with 1” slab W a v e 2 0 0 1
