Abstract: Located in high earthquake intensity, Kunming China Resources Mixc consists of a 296. 9m high super high-riseoffice building(T1 tower), a 192. 3m high super high-rise apartment building(T2 tower) and 6-story commercial podium,and energy dissipation technology was used in the T1 tower and podium. Based on the optimal principle, a series ofselections were carried out from the overall structure to the component level to determine the structural design scheme. Thelayout of different seismic joints were compared, and the T1 tower structure system, outrigger truss and belt truss ofreinforced story, outer frame column, load, beam, etc. were analyzed and selected in detail. The T2 tower structuresystem, steel inclined brace and reinforced story, transfer type of outer frame column etc. were analyzed and selected indetail. At the same time, the foundation design, shear wall design and steel concealed inclined bracing lap block design ofsuper high-rise structure with large height-width ratio in high earthquake intensity were analyzed, and take targetedmeasures to strengthen. The results show that the structure has good rigidity and strength, meets the requirements of thespecifications, and is safe, economical and reasonable.

Keywords:high earthquake intensity; super high-rise structure; seismic joint; reinforced story; brace-frame core wallstructure; steel concealed inclined bracing lap block
