Architect’s Vision
• Flexible building and workplaces
• Central areas for interaction
• Ocean view
• Context
Architect Engineer CM
New Design 1 • Undeveloped circulation• High Tech
• Clear structural grid• Possible difficulty casting slope slab
• Excavation required for Auditorium• High cost of the exterior (glass)• Possible savings by exposing slab
New Design 2
• Good organization, elegant, interesting for good detail
• Structure integrated with architecture• No visual intrusion to architectural components
• High learning curve due to the symmetry of the structure• No excavation required for auditorium

Building Performance
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

Structural Requirements
•Steel Moment resisting frame
•3” 20GA full composite slab
•12m girder, column/column span

Final Structural Solution
Beam : W18X35
Girder: W24X76
Column: W14X48
Foundation Design
W a v e 2 0 0 1
• Spread footings :1.5m X 1.5m X 60cm
• Grade beams: 30 cm X 60cm
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

Architectural/Structural Integration
Architect Engineer
•Elevator Check for beam & girder location and frame around slab opening
•Sloped slab Design supporting structure for gravity load
•Conventional Truss: Double angles
•Truss Spacing: 20’ oc
•Purlin Spacing: 5’oc EW, 7oc NS
•Simple connections to main structure

Final Roof Design: Structure
N
•Sloping N-S direction
•Suction effect due to North wind at wing trusses—uplifting
•Compression on end trusses

Structure Connections
W a v e 2 0 0 1
• P-d effect included• Story drift : 1.2 in
• Large horizontal shear force at truss/structure connection
Structural Analysis:
W a v e 2 0 0 1
• Truss element forces are verified by MASTAN
• Average element force ranging from 10 kips to 50 kips
Pro’s Cons
•Minimum space intrusion
•Flexible future upgrades
•Simple structure
• Deep beams and girderslimiting floor to ceiling height• Conservative structural member sizes
Pro’s and Cons
W a v e 2 0 0 1
• Budget: $5.5 Million in 2015 (4.6 Million PV)
• Time Constraints:
• 1 year (construction duration )
• Computer Lab Occupied by May 30, 2016
• Preserve Architecture
