Experimental study of the cyclic behavior of steel tube in concrete‐filled steel tube members

ce/papers, 2023
AbstractA concrete‐filled steel tube (CFST) specimen was tested under uniaxial loading to acquire the nonlinear monotonic and cyclic response of the steel tube in CFST members including inelastic cyclic local buckling. The failure mode, hysteretic response, envelope curves, strength, and stiffness degradation of the CFST specimen were comprehensively ...

Bearing Capacities of Different-Diameter Concrete-Filled Steel Tubes under Axial Compression

Advances in Materials Science and Engineering, 2016
The bearing capacities of concrete-filled steel tubes are normally derived through experiments with small-scale specimens, but it is uncertain whether such derivations are appropriate for the much larger components used in practical engineering.
