Resumen
The article examines the bearing capacity of the pyramid model of cross-bar spatial structures. A diagram of the arrangement of electric load cells and loads during testing of pyramids is given. The residual deformations in the controlled sections of the rods and the forces in the rods of the pyramids at the design load are given. The destruction of all experimental pyramids and the general form of the loss of stability of compressed rods in the experimental pyramids are considered. The constructive correction for the normal force is determined at all stages of testing in all pyramids.
