Using ANN to Estimate the Critical Buckling Load of Y

Feb 17,2021·Accurate measurement of the critical buckling stress is crucial in the entire field of structural engineering.In this paper,the critical buckling load of Y-shaped cross-section steel columns was predicted by the Artificial Neural Network (ANN) using the Levenberg-Marquardt algorithm.The results of 57 buckling tests were used to generate the training and testing datasets.tstresses and one coritaining residual stresses lies in the fact that both the tangent modulus and the effective moment of inertia are greater for the column free of residual stresses.Onthe other hand,the behavior of a stub column reflects only the effect of residual stresses on the tangent modulus*~ithe low values of the residual stresses observed in the specimens.These values are of the magnitudes found in hot-rolledplates of A7 steel and have practically insignificant influence on column strength.Further verification of the absence of any appreciable amount of residual stress is observed from the results of the stub column tests.
