The article presents the formulation of the non-linear bending problem in the plane of a reinforced concrete beam with a rectangular cross-section. The example structural element is the most common in engineering practice for reinforced concrete structures, which makes it an excellent representative for teaching both mechanics and reinforced concrete design. A detailed analysis of the structural working phases provides didactic material that can be treated as a bridge between theory and application and helps to understand the concept of limit states.In the typical educational process in civil engineering, there is a gap between the teaching of structural mechanics and reinforced concrete or steel structures.
Usually, theoretical subjects abstract from applications, while applied subjects concerning design do not delve into the mechanical side of modeling the behavior of structural elements. There are few textbooks that treat the bending analysis of bar elements in the non-linear range [1, 2], which are rarely referred to by lecturers of reinforced concrete structures. This article is an attempt to combine the achievements of mechanics and their application in structures using a relatively simple example. (…)
