| Abstract |
Trapezoidal-corrugated steel plate refers to a plate with horizontal and inclined panels that have been processed at a fixed angle. When this plate is used in a shear wall system, rigidity along the corrugation direction does not increase due to its accordion effect. This plate is also economical to use because it serves as a vertical stiffener. However, corrugated steel plates have orthotropic characteristics. It is also not easy to determine the corrugation shape for design because their shear performance or hysteric behavior is difficult to reveal. In this study, the hysteric behavior of a corrugated steel plate under cyclic loading was investigated and the characteristics of the corrugated steel plates of the same size were analyzed according to the corrugation depth. Results of the experiment were compared with the buckling shape through a buckling analysis of the corrugated steel plate, and the collapse mechanism under cyclic loading was examined. In conclusion, the fracture at boundary had an effect on the generation of buckling, and the specimen where shear buckling occurred showed better resistance and cumulative energy dissipation according to corrugation shape than the specimen where no shear buckling occurred. |
