The Basic Geometry
Mobius Strip (continuous loop)
Cantilever Overhang
Diagonal Structural Grid System
L-Shaped
Слайд 12Construction Challenges
What kinds of Challenges will this Project face?
Needs to accommodate
10,000 people, heavy equipment ? High service loads
Beijing is an Earthquake Prone Area (need seismic stability)
Every building encounters vertical and lateral loads
Temperature changes, material deformation
Subsoil Conditions:
Pore Water present in great amounts
High Settlement Risk

Слайд 14Diagrid Framing System
What is it?
Short for Diagonal Grid System
Triangulated structure with
diagonal
support beams
Similar to a typical moment frame
Triangles connected at Nodes and Rings intersect the nodes
Combines the benefits of a hollow tube with a truss

Слайд 15Diagrid Framing System
What is it? (cont.)
Can be constructed of either:
Steel (most
common)
Timber
Reinforced Concrete
Steel is typical because of high tensile and compressive strengths
Essentially marrying columns, diagonals and bracings into one system
Not a new technology, used in early aviation and small-scale structures

Слайд 21Miscellaneous Topics
Dealing with Wind
Wind Tunnel Experiments had to be carried out
to
assess the severity of Wind Loads
Building strength against a 100-year Wind was assessed
Method: Dynamic Analysis using High-Frequency Pressure Integration Method
285 Pressure Taps installed on 1:500 Scale Model
North and West Winds Critical
Southwest Wind worst for Vertical Loads
