COMPLEX FOR TESTING BUILDING STRUCTURES FOR BENDING WITH TORSION UNDER STATIC LONG-TERM AND SHORT-TERM EXPOSURE Russian patent published in 2023 - IPC G01N3/20 

FIELD: testing equipment.

SUBSTANCE: used in testing structures and individual elements of buildings and structures operating in bending and torsion during static long-term and short-term erection. The complex for testing building structures for bending with torsion under static long-term and short-term exposure includes a support frame, caps 10 with oppositely directed projections, fixed on the test sample 9 in specified places, and a loading device that transfers the load through the distribution beam 14 to the caps 10. In the proposed solution, the support frame, containing the base 1 and connecting beams 2, is equipped with spherical supports 4 located oppositely and coaxially on the base, while on the connecting beams 2 under the overhangs of the caps 10, movable anchor plates 12 are rigidly fixed, connected with the caps 10 by fasteners 13, and the vertical post 5, rigidly fixed on the connecting beams 2, is provided in the upper part with a transverse traverse 7, which contacts through the loading means with the distribution traverse 14.

EFFECT: expansion of functionality by obtaining reliable data on the ultimate loads and the nature of the stress-strain state of structures and individual elements of buildings and structures operating in bending with torsion under static long-term and short-term exposure.
