  • 1. Structure at the velocity of architecture ACADIA 2010 Kermin Chok, SE, PE Project Engineer Halvorson and Partners Mark Donofrio Assistant Professor University of Oregon1
  • 2. UAE Pavilion - Foster and Partners1 Dubai - ASGG EP7 - ASGG Project Examples 2
  • 3. In this environment • How do we accelerate structural design? • Can we effectively support the design intent? • Is it possible to expand the design space? 3
  • 4. Presentation Overview• Traditional Workflow• Halvorson and Partners Workflow• Geometry• Database/Script Centric Workflow• Form Finding• Expanding the design space• Optimization• Visualizations• Parametric Structural Analysis Presentation Overview 4
  • 5. Traditional Workflow5
  • 6. Current challenges Goals • Architectural vs structural geometry • Unify geometry platforms • Interoperability • Custom scripts for interoperability • Point and click approach • Accelerating the design process • Change management • Change Management • Broaden the design space • Enhanced Collaboration Digital Design Challenges and Goals 6
  • 7. Speed Concept Design Schematic Design Design Development Construction Documents Construction Admin Project Timeline Digital Design Trade-offs 7
  • 8. HP Workflow8
  • 9. • Architecture - surfaces • Structure - discrete elements ͳ Separate beam and wall properties ͳ Group elements by tier ͳ Regroup by structural demandsArchitectural Massing Structural Geometry 3400 Beam elements 115 Beam properties Parametric Grasshopper Model Architectural vs Structural Geometry 9
  • 10. • Adapting to large datasets ͳ Generation of load combinations • Change management ͳ Accumulation of design knowledge • Sub modeling ͳ Detailed sub models in synch with global model • Design team collaboration ͳ Parrallel post processing of analysis results Records: 59520 Max 158 284 65 131 79 428 HSS 30x0.75 Min ‐840 ‐284 ‐59 ‐714 ‐93 ‐160 Type Capacity Phi Design  Beam ID LoadCase Position Axial M1 V1 M2 V2 T Prop Name Story Axial Stress Shear Stress End Comp. ‐2504 0.9 Comp.
