균등휨을 받는 경량H형강보의 횡좌굴내력 ( A Study on the Lateral Buckling Strength of Light Weight H-shaped Steel Beams under Uniform Moment )

The inelastic lateral buckling strength of light weight H-type section beams, which are cold-formed and arc-welded, is evaluated under pure bending moment. The testing results are compared with the numerical analysis results using stub column curves based on the tangent modulus load. And the applications of SSRC method and current design code are discussed.
