Abstract: Tsingdao Wanbang Center is 2324m high, which is designed as steel concrete mixed structure. The whole structure is made up of diagonal brace frame and core wall. The mechanics performance of the diagonal brace frame system is introduced. Based on the analysis, its anti-seismic performance and seismic fortification measures for the structure are summarized. Finally, the design of representational complicated connections in the project is introduced. All of this can provide reference for the similar project.

Keywords: tall building； brace-frame and core wall structure； seismic performance； design of connections
