In this paper, elasto-plastic torsional response behavior of eccentric steel structures with flexible-stiff mixed frames are investigated by shaking table tests and dynamic response analyses. The principal conclusions are summarized as follows ; 1) Eccentricity has no influence on total input energy to the specimens. 2) The torsional responses amplify the cumulative inelastic deformation ratios of the stiff members. The amplification factor of each specimen can be estimated. 3) The amplification factor of the cumulative inelastic deformation ratio is greater than that of the ductility factor. It is dangerous for earthquake resistant design to estimate the damage by an earthquake based on the increase of the ductility factor. 4) Compared with the test results, it is demonstrated that the results of response analyses without damping agree with the actual phenomena.
