| Abstract: | In this paper, when the beam was applied with eccentric force, the finite element analysis technique was used to calculate the maximum stress peak in the combined beams section. For the combined beams of the steel structure engineering while the beams are mounted and are not mounted web stiffener, and the results were that the stress peak in web stiffener of the beams section can be reduced remarkable, finally, it provided the detail items for the designing of beams. |

| Keywords: | combination beam eccentricity force finite element method stress deformation. |
