Abstract:Tower A of Guiyang World Trade Center has a total structural height of 381m, and it adopts the dense column frame-corewall structural system by using reinforced concrete frame column with built-in steel rods and reinforced concrete corewall with built-in steel tubes. In view of its shape with “larger lower part and smaller upper part”, the plane size of the corewall is reduced upward by gently inclined outer frame column and inclined wall transition in the interior. The whole and special detailed analysis of this super high-rise frame-corewall structure was carried out. As a stiffness control index, the overall stability meets the requirements, and the seismic performance design meets the requirements of the code. 

Keywords:Guiyang World Trade Center; dense column frame-corewall structure; overall stability; modified rigid-gravity ratio; column with built-in steel rod; steel tube shear wall
