By the end of 2014, the numbers of super-tall buildings above 250m completed and under construction in China have reached 90 and 129 respectively. China has become one of the centers of super-tall buildings in the world. Super-tall buildings in china become higher, more slender and more complex. Structural design focuses on the efficiency of lateral resisting system and application of energy dissipation. Furthermore, the research, design and construction of high-performance materials, pile foundation, mega-member has made a lot of progress. Meanwhile, more and more new challenges are presented: the improvement of the efficiency of structural system, the further understanding of failure model of structure, the definition of design criteria, the application of high performance material and the construction monitoring. The local structural engineers played a more important role in the super-tall buildings design.
