| Abstract |
Many researches have been performed to describe the elastic and inelastic behavior of H-shaped beams with web openings, and were generally concentrated on the monotonic loading conditions. In this experimental study, local buckling behaviour of welded light H-shaped beams with web openings under cyclic loading were investigated, and the adequacy of design method of web openings beams proposed by Darwin was examined. The commencement and the effect of local buckling, the strength and stiffness deterioration after local buckling, and the fracture around the web openings under cyclic loading condition were also investigated through the observation of the test results with various openings with or without stiffeners. |
