Load-carrying capacity of circular concrete filled steel tubes under axial loading: Reliability analyses

Prediction of axial load capacity of stub circular concrete-filled steel tube using fuzzy logic

a r t i c l e i n f o Keywords: Concrete-filled steel tube (CFST) Confinement effect Fuzzy logic Modified learning from example (MLFE) Axial load capacity A circular concrete-filled steel tube (CFST) has several advantages compared with the conventional reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and str...

Numerical Analysis of Concrete-Filled Circular Steel Tubes

Numerical Crashworthiness Analysis of Graded Layered Foam- Filled Tubes Under Axial Loading

In this article, the results of a study on energy absorption characteristics of foam-filled thin-walled structures with finite element analysis have been presented. Four specimens of thin walled structures have been filled with uniform foam and three specimens have been filled with linear four-layered foam. Also, eight layers HLH (High-Low-High) and eight layers LHL (Low-High-Low) have been sim...

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...
