摘要：
The purpose of this paper is to propose the elastic-plastic hysteretic model of laterally unsupported H-shaped steel beams under cyclic loading. We designed the experiment system which can ensure rigorous boundary conditions for lateral-buckling tests of H-shaped steel beams in large deformation regime. Twenty four beam specimens are employed to observe the effect of the moment gradient and slenderness ratio for the hysteretic behavior. Based on the test results, the basic mechanisms of hysteretic behavior of H-shaped steel beams under cyclic loading is clarified, and the elactic-plastic hysteretic model is proposed. © 2015, Architectural Institute of Japan.
