Concrete-Filled Steel Tube (CFST) columns need to be reliably analyzed and estimated under axial compression. This research contributes solving the above problem by using an integrated Ansys Workbench application, DesignXplorer. approach is convenient for academics industry in CFST column design because proposed compressive strength formulas will established parameters’ properties. Correlation ...

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...
