To study the seismic behavior of I-shaped concrete filled steel tube (CFT) frame column-steel plate composite shear wall, three specimens were tested under axial continuous compressive pressure and horizontal low cyclic loading. The influence of embedded steel plate, concealed steel bar bracing, uncovered double steel plate, on the seismic behavior was investigated. Test shows that concealed steel bar bracing can increase bearing capacity, deformability and energy dissipating ability of the I-shaped composite shear wall; but the steel ratio will increase in some degree. With an equal steel ratio of the embedded steel plate composite shear wall, the uncovered double steel plate composite shear wall possesses a litter lower bearing capacity and stiffness;but the deformability increase significantly. The studied I-shaped CFT frame column-steel plate composite shear wall possesses well yielding mechanics and multiple seismic fortification lines. Thus they can be used in high rise buildings. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology. All right reserved.
