Gap study on concrete filled steel tube (CFST) and concrete filled double steel tube (CFDST) columns subjected to blast loads. [PDF]
Sci RepAbstract Columns are essential structural components that must be assessed for potential hazards, including blast loads. Such loads pose significant risks to both civil and military infrastructure, whether caused by terrorist attacks or accidental explosions. This study conducts a comprehensive review of existing research on the blast

Damage Detection Using Ultrasonic Techniques in Concrete-Filled Steel Tubes (CFSTs) Columns
Sensors, 2022 Concrete-filled steel tubes (CFSTs) are structural elements that, as a consequence of an incorrect elaboration, can exhibit internal defects that cannot be visualized, being usually air voids. In this work, the detection of internal damage in CFST samples elaborated with a percentage of contained air voids in concrete, was carried out by performing a ...

Innovative shear transfer system for Concrete Filled Steel Tubes (CFST) in columns
ce/papers, 2021 AbstractThe common failure mode of composite steel‐concrete structural elements, such as composite columns, generally occurs due to the relative slipping or separation of the steel sheet and the concrete. This leads to materials overspending and low resistance.
