Computer Security Analysis of Large-Panel Buildings Resulting From the Cooperation of the Building With the Elastic Half-Space of the Soil Center With the Possible Scratching of the Reinforced Concrete Composite

Abstract

The work touches on the national security issues of large-panel buildings from the point of view of settlement of the building on the ground. Displacements of the structure in the level of foundation of the building structure cause the secondary distribution of stresses, thus the possibility of structural scratches of internal prefabricated plate elements. The original model FEM of the construction of the large-panel building system Wk-70, which was built for research purposes, allowed the approximation of the phenomenon contained in the title of this work. Awareness of the safety of the construction of buildings implemented in large-panel technology is very important and constitutes a significant overtone, not only structural, but also general social.

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

“…The theoretical shell model, Fig. 1, not only takes into account the rigid-spatial global operation of the structure, but also represents cooperation with the elastic half-space of the soil medium [8,9,10,11,12,13]. The last one allows to monitor displacements and, as a result, to determine the place of possible scratch formation -in the zone (s) of the most interactively accumulated displacements caused by subsidence.…”

“…The actual picture of the state of stress in the structure of a large-panel building becomes more accurate using the FEM shell model. It should be emphasized that the developed results were reflected for the stiffening diaphragm, which together with the vertical communication structure [8,9], constitutes the stiffening core of the building structure. According to the works [3,4], in the structural system of such a wall, flexible joints are not used, which often occur in prefabricated buildings, and then their elastic nature is a non-linear graph M -φ (bending moment -angle of rotation of the deformed axis of the ceiling disk, resulting from the differential equation of the ceiling deflection line).…”
