EFFECT OF LOCAL CONCAVITY UPON BEARING SHELL OF HIGH BUILDINGS
This article describes one of the types of geometric deviations - concavity. Also the parameters that characterize it are defined. In addition, the results of numerical studies of the effect on the local concavity of the stress-strain-state of shells of high buildings. The field of distribution of ring and meridian stresses in the investigated area is shown. The zones of influence on the concavity of the bearing shell of high buildings. It is also determined by carrying capacity of the barrel sections of high-rise structures with different geometries and different parameters of the concavity of the investigated membranes. The data obtained have been used to explore the dependence of reduction of the carrying capacity of the concave size, diameter and thickness of shells of high buildings.
