Abstract: E09 main tower with the total height of 173 meters is located in Beijing Lize CBD core area, E-09, and adopt steel concentrically braced frame system. It focuses on introducing the structural system of main tower, modal analysis, wind analysis, seismic analysis, and linear buckling analysis. This project can give reference to the similar design.

Keywords: high-rise steel structure; concentrically braced frame
