Abstract:

The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted on this suspen-dome system. The test models used were circular, with a diameter of 3.0 m. Brass pipes were employed for the single-layer trusses, and steel rods for the cable systems. The results of the tests, by controlled loading, confirmed that the incremental axial stresses in the dome truss members were smaller in the suspen-dome than in the single-layer truss dome. In the buckling test, the suspen-dome was found to have a buckling load 1.5 to 1.8 times that of the single-layer truss dome.
