Abstract
Aiming at the major needs of China's new urbanization construction and high-intensity seismic fortification area,this project has carried out systematic research on the key scientific and technical problems of the built-in tensioned concrete-filled steel tube column and its structural system from many aspects,such as experimental research,theoretical analysis,strengthening technology and engineering application.The theory of constraint coefficient of reinforced concrete filled steel tube(CFST)column and its structure system is put forward,which realizes the goals of good seismic performance,low construction cost,high efficiency,better quality,green environmental protection and energy saving,and obtains remarkable economic and social benefits.
