A Study on the Strength Properties of High Performance Concrete Filled Steel Tube Column : The Behavior Properties by Strength of Concrete |
| Abstract |
The concrete filled steel tube structure have many excellent structural =roperties, such as high load carrying capacity and plastic deformation capacity. Improvement of fire-resistance properties and restriction of local buckling of steel tube, as to gromote improvement of structural capacity to demonstrate heterogeneous material properties interdependently. Under these background, many scholars investigated to structural properties of concrete fiIIed steel tube column, like as relaxation of Bt ratio restriction by confined effect of concrete and estimated formula of deformation, considered column axial force. But it has not been clearly established as concrete in steel tube up to now. Based on previous results, this study investigated to Droperties of structural behaviors through a series of exDeriments for high performance concrete filed steel tube column with key parameters, such as strength of concrete, eccentric ratio and B/t ratio. |
