현실적인 구속과 하중조건에서 H형강보의 횡좌굴에 관한 연구(1) - 재단구속에 관하여 ( A Study on the Lateral Buckling of H-section Steel Beams under Practical Restraints and Loading Conditions(1) )

Lateral buckling strength of beams depends on various restraints conditions. The present design formulas, however do not cover a large variety of restraining conditions and they are rather complex. In this paper an advanced design formulas for the beam with doubly symmetrical H-section is suggested and the effects of various restraining conditions are investigated. To verify the proposed formular experimentaly, 36 H-section beams which have different slenderness ratios are tested by apllying pure bending moment. As the result of the experiments the buckling behavior of H-section beams is clarified.
