Experimental Study on Compressive Behavior of Concrete-filled Double-skin Circular Tubes with Active Confinement

نویسندگان

چکیده

A convenient family member of composite columns is concrete filled double skin tube (CFDST); it contains two tubes concentric steel and also shell that there between them. The superior or equal potential offering characteristics CFDST are more than counterparts classical (CFST). purposes the present study to provide experimental investigation results into prestressed load-carrying capacity columns. Here, an innovative technique used confined prestressing, in which fresh compressed for a short-run duration. Sixty-four total specimens were tested with various outer thickness diameter, inner strength resist axial compression. support concrete, demonstrates specimens' enhanced significantly.

Investigating of the Effect of Concrete Confinement on the Axial Performance of Circular Concrete Filled Double-Skin Steel Tubular (CFDST) Long Columns

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

Flexural Behavior of GFRP Tubes Filled with Magnetically Driven Concrete

Experimental investigation of GFRP (glass fiber reinforced polymer) tubes that were filled with magnetically driven concrete was carried out to study the flexural behavior of specimens under bending. Specimens having different cross section and lengths were tested. The test specimens were fabricated by filling magnetically driven concrete into the GFRP tubes and the concrete was vibrated using ...

Effect of Steel Confinement on Behavior of Reinforced Concrete Frame

The strength and ductility of concrete improve under multi-axial compressive stress due to confinement effect. Some parameters are effective for considering the confinement in concrete and various stress-strain models were developed by different researchers. Longitudinal and transverse reinforcement steels can influence on confinement in reinforced concrete members. In this paper, various stres...

Effect of the Concrete Strength on the Concrete-Steel Bond in Concrete Filled Steel Tubes

In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...
