Development of classification for bearing system prestressed structures
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 1
Abstract
The prestressing of structures means various techniques of directional artificial stress regulation or stress-strain state regulation within the structures, performed with the objective to increase their efficiency in the load accommodation during the stages of the service life. Moreover, the interference with the normal work of the object for directional change of its deformation potential energy can be carried out at different stages of its life cycle (during its manufacturing process, mounting, operations or reconstruction) and at different levels. The current paper is devoted to systematizing information on the classification and application of prestressed structures for bearing systems in various fields of engineering. It also analyzes theoretical and practical peculiarities of modern designs of prestressed structures as well as some specific issues of their use. The capabilities and the analysis of prospects for prestressed bearing structures in railway engineering, particularly in the construction of freight cars, are revealed. To implement prestressed blocks and elements is rational in the freight cars constructions. However, the effective introduction of the above mentioned is only possible on the basis of scientific grounding for the structure and parameters of appropriate engineering solutions.
