This paper introduces the development of super high rise buildings and emphasizes in introducing a new structure system—super structure′s conception、development、characteristics and project examples.

In this paper,the concept of mega structures and classification are introduced,so as to classic buildings of every category in the world.

Types of the commonly used mega structure system are introduced,by taking advantage of both the mega frame structure and mega truss structure,the mega braced frame structure system is proposed.

According to the trend of the development of high rise buildings,the concepts,characteristics,classification and applications of mega structures are presented in the paper.

It is necessary to carry on the research with respect to megastructure with more and more highrise buildings constructed all over the world.

Based on the lateral force resisting system of high rise building, through abundant examples, this paper analyzes the types and internal force characteristics of megastructure systems.

Present state and perspectives of research on mega-structure foundation;

At present,when the mega-structure system being designed,"truss effect" between mega-frame and sub-frames is been thought increasingly.

The main advantage of mega-structure is high capacity to resist lateral loads.
