shaking table tests on a 1:12 scale model to investigate the seismic performance of a 17-story RC high-rise struc-ture, with a high degree of torsional eccentricity and soft-story irregularities in the bottom two stories. Ye et al. (2004) do shaking table to test on a RC structure. Jiang et al. (2005) carried out shaking table test on an irregular
