When a structure subjected an external loading, it results in internal stresses. Structural analysis concerned with this result includes determining the magnitude of the reactions, internal forces and displacement. Computational results by finite element analysis (FEA) of structural steel are displayed in a variety of mesh size element and material type. Finite element analysis (FEA) nonlinear was carried out using ANSYS. In this work, nonlinear analysis is applied to materials structural steel grade SS400; SS490; and SS540 with a cross section wide flange (W). Variations of the mesh size element are 8 mm; 6mm; and 4 mm. Finite element analysis (FEA) are done by applying the variable load pressure on section area of materials under fixed support condition. The stress-strain curve and yielding point are knowing for each variation. Von-Mises stress increased with the reduction of mesh size element. Von Mises stress under any load conditions showed good results on steel grade SS540 with the same thickness. © 2023 The Authors. Published by ELSEVIER B.V.
