Abstract:Shanghai World Financial Center is a super highrise building with 492 meters height. The building consisting of 3 stories underground and 101 stories overground will be the tallest building in China. This building uses the structural system with a megatruss tube outside and a RC tube as a core. This paper puts emphasis on the system characteristic, performancebased calculation principle and design methods of this project, the main result of static analysis and static pushover analysis with overall structural of building, the experimental result of the overall model and connection model,transfer of core wall,the design of outrigger which can not go through the corewall, design principle of belt truss,mega diagonal and perimeter small steel column, special connection design for box shaped component,top steel structure and setting of energy dissipation equipment etc,to offer reference on the design of the projects of this kind.
