【 摘 要 】

The results of experimental studies and numerical analysis of reinforced concrete space fragment frame high-rise building to the limit and beyond. The calculation of these construction systems are made in a constructive and physically nonlinear formulation. As a design uses two-level scheme, which is used to calculate the specified design load in the algorithm at the first stage, and in the second stage for the beyond design basis impact caused by a sudden emergency shutdown of one of the frame struts. The features of composite beams deformation, as part of the structural system before and after beyond design basis exposure, cause a sudden structural adjustment the structural system. We obtained the satisfactory agreement of calculation results by the proposed algorithm to analyze the deformation of physically and structurally nonlinear reinforced concrete space frames with structures' test result.
