- Abstract
The Effect of horizontal strengthened story to the seismic response of super high - rise steel braced frame is analyzed in this paper through the finite element software ANSYS. By comparison of six different schemes of a 32 - story building, further research is presented on the influence of the quantity of strengthened story to the lateral stiffness, the inner force of components under earthquake and the distribution of shear force among inner tube and outer frame. According to the study, the Wuhan International Securities Mansion, which is a super high -rise steel structure, is described as verification. The response of the building is analyzed in small earthquake. The study can serve as the references of super high - rise structure with horizontal strengthened story design.
