BBK 38 Строительство
The article deals with existing methods for evaluating the load bearing capacity and deformability of bent reinforced-concrete elements, including the composite section. The analysis of idealized nonlinear dependencies and compressed concrete deformation diagrams. Iterative methods for structural analysis: the method of successive refinement of stiffness, the method of successive loadings, initial stress method. Results of their algorithms and shows the advantage of using the method of the dual stiffness are considered.
flexural reinforced concrete element, stiffener, flection of the element, the iterative calculation method.
