This paper presents the design, and the examination of ductile structural behavior through finite element analyses, of super composite columns and their connections to the outriggers, double belt trusses, and mega bracing members of the Ping An International Financial Center Tower in Shenzhen, China. When completed, this 660m-tall structure will be the tallest building in China and the second tallest building in the world. Many complicated steel connections were analyzed and designed. Finite element analyses were performed on the super column, outriggers, double belt trusses, and mega bracing connections to evaluate the performance of the as-designed connections under 100 year wind forces and three levels of seismic action: frequent earthquake, moderate earthquake and severe earthquake. This paper also briefly presents the design of the steel connections; describes the ABAQUS finite element analyses model; presents the major results of the finite element analyses; and evaluates the performance of the connections based on the analysis results.
