Abstract
The development of methods for the calculating reinforced concrete structures covers a wide range of issues, including the expansion of the application of new innovative materials such as concrete and reinforcement. For usage in the practice of modern construction of multilayer structures made of concrete with different physic-mechanical characteristics, it is compulsory to conduct numerical studies of the stress-strain state of these structures under different types of loading. This article presents an analysis of the influence of the relations between the initial elastic modulus of the outer and middle layers for the stress-strain state and the deflection of three-layer reinforced concrete structures using the finite element method in the program ANSYS Mechanical. Numerical modeling allows comparing the obtained results and building theoretical dependences in a wide range of specified parameters for the construction of sections of multilayer reinforced concrete elements. The obtained scientific results enable to determine rational parameters for modeling various structural solutions of multilayer reinforced concrete structures. This would limit the number of actual test samples, increasing the efficiency of the experiment.
Highlights
At present, multilayer reinforced concrete structures are used in the expansion of fields
One of these is the use of multilayer reinforced concrete structures with a middle layer of low thermal conductivity concrete
In the above publications of the author [1, 3, 4], analysis have showed the relationship of the elastic modulus of the middle and outer layers, which influenced the stress and strain of multilayered concrete slab
Summary
Multilayer reinforced concrete structures are used in the expansion of fields One of these is the use of multilayer reinforced concrete structures with a middle layer of low thermal conductivity concrete. Three-layer construction with a heat-insulating layer of light concretes of low average density and strength relate to a special class of reinforced concrete structures. They occupy an intermediate position between conventional reinforced concrete structures and combined composite section with outer layers of reinforced concrete and the middle layer of different types of thermal insulation materials, characterized by low strength and high deformation. In the above publications of the author [1, 3, 4], analysis have showed the relationship of the elastic modulus of the middle and outer layers, which influenced the stress and strain of multilayered concrete slab
