- Abstract
- Many researches have been performed to described the elastic and inelastic behavior of the general steel with web opening, and were generally concentrated on the uniaxial loading conditions. With those results of researches, the formulae for design of beams with web openings have been proposed by Darwin(1990). Though the formulae are so simple and useful to apply to real situation, it needs more research on cyclic loading condition. In order to investigate the strength and deformation characteristics of H beams with web openings, 9 steel beams with web openings were tested. The dimensions of beams are based on the formulae proposed by Darwin. The suitability of existing design formulae, the effects of plastic hinges on beams with web openings, and the local bucking around the web openings to the beam strength were also investigated through the observation of the behaviors of these beams with various opening types.And the effect of local buckling, the strength and stiffness deterioration after local buckling, and fracture around the web openings under cyclic loading condition were investigated and studied through the observation of the test results with various openings with or without stiffeners.
