Verification and validation for non-linear finite element analysis of reinforced concrete beams with shear reinforcements

Abstract

This paper presents an example of the verification and validation (V&V) for non-linear finite element analysis of reinforced concrete beams with shear reinforcements subjected to four-point bending. The code verification, together with the calculation verification, is performed by comparing the numerical results obtained by changing the mesh size with a reference solution based on Euler-Bernoulli beam theory. The sensitivity analysis based on the analysis of variance with an orthogonal array is then performed to quantify the degree of influence of material parameters on the numerical results. The computational model is finally validated for its intended use by comparing the results of a Monte Carlo simulation that reflects the variation in material properties with the results obtained from a validation experiment.
