영문 초록

Buckling is a significant behavior to be considered whenever we design steel structures. In the case of H-shape beams, the lateral buckling occured by bending moment must be considered, Because of the lateral buckling of H-shape beams, the bending strength of the beams are determined by the lateral buckling stress instead of the allowable bending stress. When we use the above equations, the results are different according to the shape of beam section, and they are rather complex. In this study lateral buckling stress equation is derived, and the proposed formula(σcr(t)) is compared with above mentioned two basic and practical equations. To verify the proposed formula experimentaly, 16 H-shape beams which have different slender ratios are tested by applying pure bending momet. Through the experiments the buckling behavior of H-shape beams is clarified, and the results shows that the proposed formula(σcr(t)) is accurate enough for practcal purpose.
