A numerical model with varying passive confinement for circular and elliptical concrete-filled steel tubular columns

Lacuesta Carrión, César Damián; Romero García, Manuel Luis; Lapuebla-Ferri, Andrés; Adam Martínez, José Miguel (Editorial Universitat Politècnica de València, 2018-06-05)

[EN] In this work, a non-linear 3D numerical model to study concrete-filled tubular (CFST) columns is presented. The numerical model is capable to consider the passive confinement that occurs in the concrete core of CFST ...
Circular and square slender concrete-filled tubular columns under large eccentricities and fire

Espinós Capilla, Ana; Romero, Manuel L.; Serra Mercé, Enrique; Hospitaler Pérez, Antonio (Elsevier, 2015-07)

Previous investigations have revealed the unsafety of the current calculation methods in Eurocode 4 for evaluating the fire resistance of concrete-filled steel tubular (CFST) columns, which has given place to a movement ...
Experimental investigation on the fire behaviour of rectangular and elliptical slender concrete-filled tubular columns

Espinós Capilla, Ana; Romero, Manuel L.; Serra Mercé, Enrique; Hospitaler Pérez, Antonio (Elsevier, 2015-08)

While the fire behaviour of concrete-filled steel tubular (CFST) columns with circular and square cross-section has been well established based on experimental programs and numerical investigations, the information about ...
Experimental study of high strength concrete-filled circular tubular columns under eccentric loading

Portoles, J.M.; Romero, Manuel L.; Bonet Senach, José Luís; Filippou, F.C. (Elsevier, 2011-04)

The paper describes 37 tests conducted on slender circular tubular columns filled with normal and high strength concrete subjected to eccentric axial load. The test parameters were the nominal strength of concrete (30, 70 ...
Influence of ultra-high strength infill in slender concrete-filled steel tubular columns

Portoles Flaj, José Manuel; Serra Mercé, Enrique; Romero, Manuel L. (Elsevier, 2013-07)

This paper describes 24 tests conducted on slender circular tubular columns filled with normal, high, and ultra-high strength concrete for plain, bar reinforced and steel fiber reinforced columns. These were reinforced and ...
Proposal of a new method in EN1994-1-2 for the fire design of concrete-filled steel tubular columns

Albero Gabarda, Vicente; Espinós Capilla, Ana; Romero, Manuel L.; Hospitaler Pérez, Antonio; Bihina, Gisèle; Renaud, Christophe (Elsevier, 2016)

Previous investigations proved the unsafety of the current design guidelines in Annex H of EN 1994-1-2 for the calculation of the fire resistance of slender concrete-filled steel tubular (CFST) columns. In this paper, a ...
Simulation and design recommendations of eccentrically loaded slender concrete-filled tubular columns

Portoles Flaj, José Manuel; Romero, Manuel L.; Filippou, Filip C.; Bonet Senach, José Luís (Elsevier, 2011-05)

This paper proposes an efficient numerical model for the simulation of the behavior of slender circular concrete-filled tubular columns subjected to eccentric axial load with single curvature, for the cases of both normal ...
Ultimate capacity of rectangular concrete-filled steel tubular columns under unequal load eccentricities

Hernández Figueirido, David; Romero, Manuel L.; Bonet Senach, José Luís; Montalva Subirats, José Miguel (Elsevier, 2012-01)

The paper describes 36 experimental tests conducted on rectangular and square tubular columns filled with normal and high strength concrete and subjected to a non-constant bending moment distribution with respect to the ...
