Summary of seismic research of mega steel structures;

On the basis of these, the paper studies profoundly the influence on response, seismic design method and seismic behavior of the mega steel structures from the floor stiffness and hypo-frame.

This paper commences from the concept, characteristics of mega structure, put forward the design principle of the mega steel structure joint on the foundation of the analysis to different joint characteristics.

Failure mode analysis of super-tall huge steel frame structure

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.
