Influence of Technological Factors on the State of Stress and Strain in Three-layer Reinforced Concrete Structures

The layered structures are the most efficient building structure elements that distinguish as lightweight and serves for both structural and thermal insulation purposes. The effective performance of all layers is very important condition for the layered structures during its service. The influence of various technological factors on the quality of the layered structures is analysed in this paper. Such technological factors include the quality of the bond between the layers, the composition and processing of the materials used for the layers, different shrinkage strains of the different layers, reinforcement ratio etc. The calculation method and equations for calculating the initial state of stress and strain caused by the concrete shrinkage are presented in the article.
