A. The long curved trusses are restrained against tipping over side-ways by the shorter trusses running between them.
B. The long, curved trusses are tubular trusses that are laterally much more stable than typical planar trusses.
C. The multiple struts supporting the curved roof truss act collectively like bi-pod, flagpole columns relative to movement of the structure parallel to the long direction of the curved trusses
E. The multiple struts supporting the curved roof trusses act collectively like bi-pod, table-leg columns relative to movement of the structure parallel to the long direction of the curved trusses.
