Abstract:The innovative design and research of new composite components, new mixed structural systems and new key nodes applied in high-rise buildings in recent years were summarized, and some engineering application examples were listed. At the same time, the design index requirements of the new concept of structural design of the mixed structure with more steel structure attributes proposed firstly in Guangdong standard Technical specification for steel-concrete mixed structure of tall buildings (DBJ/T 15-128—2017) were introduced. In view of the insufficient research on the comprehensive system of mixed structures at the current stage, it was proposed that further research work on the development of high-rise steel-concrete mixed structures is needed.

Keywords:high-rise building; steel-concrete mixed structure; new composite component; new mixed structural system; new key node; engineering application
