As previously discussed, decreasing the mesh size element may take longer computing time (Fajri et al., 2021; Prabowo and Sohn, 2019; Dutt, 2015). Calculation accuracy for hexahedral mesh elements is higher than for tetrahedral elements. (Liu et al., 2011). The result of von Mises stress of structural steel grade SS490 with various meh size elements can be seen in Fig. 6. Von Mises stress is a value used to determine the yielding of materials. If the material under load is equal to or heavier than the yield limit, the material will yield.

Fig. 7. Contour Von-Mises Stresses in (a) load start; (b) maximum value; and (c) load release.

The material was given by load until it reached the maximum value, and then the loads were released. The contour of von Mises stresses from start load and release load can be seen in Fig. 7. Contour von Mises displays the results of a single data over the model geometry. The displacement contour shows that the maximum stress occurs one second after loading. The maximum von Mises stress is estimated with time, and the load applied to the material. 6. Conclusions This paper discusses the non-linear finite element method for structural steel analysis. Structural steel was used to support structural engineering build. This study’s focus on structural analysis concerns the results of forces and displacements in the material. The mesh size element affects the results of ANSYS analysis. In addition, the type of mesh can also affect the impact of the finite element analysis. Von-Mises stress increased with the reduction of mesh size element. Von-Mises stress under any load conditions showed promising results on structural steel grade SS540 with the same thickness caused by higher yield strength than other materials. Von-Mises stress is a value used to determine the yielding of materials. The difference in von Mises stress in every material type is affected by the mechanical properties.
