Annotation: The limiting states of the reinforced concrete floor belt of the wall of a frameless building are investigated in case of uneven settlements of foundations as a result of uneven compressibility of the foundation soils or from special influences, for example, the curvature of the earth’s surface during the development of the territory. Field studies have established that the floor belt above the openings in the wall undergoes bending deformations and, in the limiting state, collapses along normal or inclined sections. The forms of destruction depend on the belt reinforcement scheme. Signs of destruction can be: flow followed by rupture of the stretched reinforcement; the ultimate compressibility of the concrete in the compressed zone; flow followed by rupture of the clamps. The aim of the research is to establish reliable deformation criteria for the limiting states of reinforced concrete floor belts of frameless buildings on unevenly deformable foundations. Re-search methods are numerical studies of a finite element design model based on the hypotheses of the theory of plastic flow of concrete.
Keywords: relative settlements, theory of plastic flow, deformation criteria.
