The article presents methodology and results of experimental investigation of full-scale steel and concrete composite cable space frame 5.3 m on effect short-term loading. The experimental sample consisted of flexible elements of the lower belt and steel and concrete composite space modules. Elements of the lower belt were made of pieces of rolled steel with a circular cross section of 16 mm in diameter. The steel and concrete composite space module was in the form of a regular rectangular pyramid of 0.5 m high and length of a side of 0.8 m, and consisted of a reinforced concrete slab of 50 mm thick and grids of steel tubular rods with an outer diameter of 42 mm and a wall thickness of 3 mm. The experimental research technique provided for measuring the structural deformations at a load that was 70% of the destructive load. As a result of the experimental test, data were obtained, on the basis of the data analysis the dependencies between deformation and loading were obtained. It was found that the studied structure during the test demonstrated the collaboration of all its components.
