The study aims at investigating the rotational capacity of H-shaped steel beams analytically and experimentally, of which strength are dependent on the lateral buckling. Secant modulus concept is used to calculate the moment-curvature relations of buckling strength and tangent modulus theory is used. Numerical analysis results are compared with test results on the loading condition of pure bending and 3-point bending.
