When the bearing is running, its clearance is no longer equal to the initial one, as a result of the thermal regime and load. This paper presents a calculation method which takes into consideration the temperature distribution in the bearing, the load, and the elastic properties of the materials. The deduced calculus relations allow to establish the correction of the initial radial clearance in order to obtain the designed clearance when the bearing is running.

The article offers a method and program for experimental studies of reinforced concrete structures with cross-shaped spatial crack under torsion with bending, the main purpose of which is to check the design assumptions and experimental determination of the design parameters of the proposed calculation method. The conducted experimental studies provide an opportunity to test the proposed calculation apparatus and clarify the regularities for determining deflections, angles of rotation of extreme sections, and stresses in the compressed zone of concrete. For analysis, the article presents a typical experimental scheme for the formation and development of cracks in the form of a sweep, as well as characteristic graphs of the dependence of the angles of rotation of end sections.
