초록
In this study, we compare and analyze stress and vertical deflectional displacement according to cross sectional shape changes of the beam using finite element analysis. The 11,000mm long horizontal beam showed stress differences depending on the cross-sectional variation, with stress differences of up to 200MPa and at least 149MPa. The deflection at the end of the beam also differed by up to 586 mm and at least 208mm. The weight change applied according to the cross-sectional shape of the steel horizontal beam was up to 235kgf, at least 144kgf, and showed the best stress and deflection characteristics in the cross sectional shape with a weight of 185kgf. This allowed us to improve structural safety through sectional shape optimization despite the weight increase.
