Abstract
Concrete-filled tubes are being increasingly used in architecture due to their improved ductility and strength under combined forces, especially under compression. However, in some specific situations, these sections may be not completely optimal from different points of view, such as in terms of fire protection or slenderness. The fact of locating the entire area of steel in the periphery of the section leads to have this material exposed to fire. Although the concrete filling plays a decisive ...
