Author's Method of Continuum States on the Example of Imperfection in the Construction of a Large-Panel Building

Abstract

The paper presents the results of FEM computer analysis regarding cracking of the wall prefabricated element. The proprietary coating model of the Wk-70 System large-panel building construction was used. For analysis, a construction diaphragm has been separated that is integrally connected to the vertical communication structure. Modeled through the scratch in the attic wall and compared with the wall model without damage. By building the shell model, a real and transparent picture of the static work of the structure was obtained, distinguishing zones: focus, redistribution, compensation and neutralization of stresses, whose genesis results from imperfection - scratches in a reinforced concrete composite. For the first time, the author introduces his own method of assessing the safety status of large-panel buildings - by the States Continuum Method.

Non-dimensional method of capacity limit states for the assessment of the safety level in the structures of large panel buildings.

“…Particular attention should be paid to the redistribution of stresses and the formation characteristics of secondary normal stress systems σ [N / mm 2 ]. More about it was written in the author's arguments [3][4][5][6][7].…”

“…The paper presents an original method of describing the safety condition of the construction of large-panel buildings. The Dimensionless Ultimate Limit States Method, which was developed on the basis of computer studies of stress redistribution in large-panel buildings [3][4][5][6][7], may be a new look at the safety of the construction of large-panel buildings.…”
