Abstract: New Development Bank Headquarters tower adopts concrete?filled steel tubular column frame?core tube structuresystem. The outer frame columns were made of concrete?filled steel tubular columns and were evenly arranged along the 6corners of the plane; the outer frame beams were made of steel trusses, which are set on the 8th, 14th, 20th, and 26thfloors to form ring?belt trusses , which together with the outer frame columns form a giant outer frame. The plane of the coretube is hexagonal and steel frames were arranged at 6 corners. The tower is designed based on domestic and foreignstructural design standards and industry standards such as bank, health materials and indoor environment, and takes thehigh integration of architecture and structure as the design goal and concept, forming a giant frame?core tube structuresystem. Through the use of structural seismic performance?based design methods, as well as special analysis methods suchas finite element analysis of key joints considering continuous collapse prevention design & seismic performance?baseddesign, and pedestrian vibration comfort analysis, it is studied and verified that the structural system under the stresscharacteristics of the giant frame is suitable for this structure. The applicability and rationality of the project have achievedthe predetermined goals of high design standards, high integration, and excellent structural performance for the BRICSBank tower.

Keywords:concrete?filled steel tubular column; ring belt truss; giant outer frame; seismic performance design; finiteelement analysis of joint
