A concise hysteretic model of structural steel considering the Bauschinger effect
Abstract This study proposes a concise hysteretic model of structural steel that is effective at simulating the mechanical behaviour of steel components. A series of plate element specimens made of SS400 structural steel were tested under diverse cyclic axial strain loadings. The hysteresis loops of the specimens are decomposed into skeleton curves and Bauschinger parts. The hysteretic model, which is composed of the skeleton curve, the Bauschinger part, and the elastic unloading part, is proposed based on the test results. To verify the effectiveness of the proposed hysteretic model, three simply supported beam specimens were tested under cyclic loadings. In addition, numerical analyses of the beams were performed using the proposed hysteretic model. The analytical results were compared with the experimental results, and the overall load-deformation relationships and the local strain histories show a good correspondence.
