Abstract

Abstract

Displacement-based seismic design method of concrete filled circular steel tube columns has been researched.The basic procedure,the key problems such as equivalent stiffness and damping ratio,the detail design procedure of CFT columns and the main factors related were summarized.Results show that: stiffness of the second stage has little effect on hysteretic damping ratio. As the increasing of axial loading ratio,thickness of steel tube increases and displacement ductility of CFT column also increases.As the increasing of the dimension of CFT column,thickness of steel tube and yield moment decrease.
- CFST column,
- performance-based design,
