Abstract

The study analysed the flexural behaviour of beams by comparing classical Euler-Bernoulli theory, finite element analysis (FEA) and experimental validation; within this framework, the objective was to carry out a comparative assessment of the flexural behaviour of beams using theory and FEA. Using a quantitative approach with an experimental design, deformations and stresses were evaluated in ASTM A36 steel specimens subjected to different loads. The results showed agreement in stresses between theory and FEA, whilst for deformations, FEA underestimated the values and the experimental results slightly overestimated them. Furthermore, a high correlation was found between the methods, validating their consistency. It was concluded that both approaches are complementary in structural analysis.
