what kind of truss is this?
can anyone tell me what kind of truss is shown in the attached picture and how it is build.
from what i can see it doesn't look like a truss at all but maybe some tying members across a hip a rafter type construction with some curved   
it is not a truss.  it looks like a variation of a geodesic, curved plate structure.
ps....it is like a proprietary design.
pps...meant to say "it is likely a proprietary design"
a structural engineer's attempt at bad architecture?  primitive honeycomb structure?
i see similar construction in the tacoma dome, but based on triangles rather than the parallellograms shown here.  i also see hip and ridge beams here, and i use the term "beams" loosely, very loosely.

maybe diamond truss system?
thanks to all that responded. this is a very interesting structure in that it is self supporting and relies on adjacent members for support.  it appears that each   
to me this looks like a barrel vault with curved ends.  the roof beams are diagonal instead of parallel to the axis of the vault.  there appears to be a longitudinal   
i would describe this as a waffle shell, or ribbed shell structural system.  good luck.
this is what is called a lamella roof, i believe.
