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...
متن کاملExperimental and Numerical Study on Bar-Reinforced Concrete Filled Steel Tubular Columns Under Axial Compression
The behaviors of bar-reinforced concrete filled steel tubular columns subjected to axial load were studied. One plain concrete filled steel tubular column and three bar-reinforced concrete filled steel tubular columns were tested. The deformation of specimens and the strain of steel tubes were measured. Based on experimental researches, a simple numerical analysis method was presented to simula...
متن کاملInvestigating 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...
متن کاملConcrete Filled Tubular Bracing Subjected to Cyclic Loading
The energy absorption of concrete filled, hollow-steel bracing was analyzed respect to geometric and mechanical parameters including the width-to-thickness section ratio, slenderness level, and strength of the steel and concrete. Local buckling and ductility were also investigated with respect to variation in the cross-section. The infill increased the compression resistance, even after multipl...
متن کاملInelastic Behavior of Concrete-filled Thin-walled Steel Tubular Columns Subjected to Local Buckling
This paper is concerned with the inelastic behavior of axially loaded concrete-filled thin-walled steel tubular columns subjected to local buckling. A nonlinear fiber element analysis program accounting for local buckling effects is developed for predicting the ultimate strength and ductility of concrete-filled thin-walled steel tubular columns. The effects of local buckling are taken into cons...
