Abstract: A new frame?damping frame tube structural system consisting of outer frame, inner frame and damping wall wasproposed. The contributions of the damping wall to the stiffness and damping of the structural system were analyzed, thenthe corresponding theoretical formulas were derived. A high bearing capacity damping wall was developed, the high bearingand energy dissipation capacity were demonstrated through low cyclic loading tests of two full?scale specimens. The seismicperformance of the frame?damping frame tube structural system was studied through low cyclic loading tests of two 1?span,2?story, 1 / 2 scale models. The results show that the frame?damping frame tube structural system has excellent seismicperformance and can be applied to super high?rise buildings.

Keywords:frame?damping frame tube structure; super high?rise structure; high bearing capacity damping wall; seismicperformance; low cyclic loading test
