Abstract
The article presents the results of experimental research and computational analysis of a reinforced concrete spatial frame - a fragment of the frame of a multi-storey building in limiting and out-of-limit states. A series of tests for design and beyond design impacts was performed at the stage of construction without cracks. The dynamic calculation of the considered structural system was carried out in the mode of direct integration of the equations of motion. The features of frame deformation before and after the beyond design basis impact, causing a sudden structural restructuring of the structural system, have been established. Satisfactory agreement of the calculation results with the test results is obtained.
