The article deals with issues related to stresses and deformation of the stiffness core of a high-rise building. This refers to the stage of working with cracks in the nonlinear work of reinforced concrete. The possibility of tracking the change in stiffness during operation is illustrated. It is shown that concrete of the stiffening core works in the plastic stage in one part of the stiffening core, with cracks from tension in the other part. Compressive and tensile stresses in the walls of the stiffening core are uneven throughout their thickness. The reserve of stiffness and strength is due to the effect of the cage of the less loaded part of the sections. The use of inclinometers for monitoring buildings allows you to track not only uneven settlements of buildings, but also deformations of the stiffness core of a high-rise building from temporary loads. The angles of rotation of the nodes of the design model were determined for various combinations of temporary loads, while there is a constant redistribution of efforts in the range of up to 50%. Monitoring by the method of inclinometers, located evenly along the height of buildings and the corners of a building or its stiffness core, makes it possible to track the development of plastic deformations of concrete of the stiffness core and the level of cracking.
