Circular concrete-filled dual steel columns with ultrahigh-strength concrete
Romero, M. L.; Albero, Vicente; Espinós, Ana; Hospitaler, Antonio; Pons, David; Portolés Flaj, Jose Manuel; Ibáñez Usach, Carmen Ernst und Sohn: OnlineOpen (2016)This paper presents the results of an experimental campaign in which the buckling resistance of 12 concrete-filled dual steel columns was ascertained. Whereas some papers in the literature describe investigations into ... -
Efecto del spalling sobre la resistencia a flexión biaxial de pilares de hormigón armado expuestos a fuego
Peña Mansilla, David Leonardo; Albero, Vicente; Ibáñez Usach, Carmen; Hospitaler, Antonio; Espinós, Ana; Romero, Manuel L. Asociación Española de Ingeniería Estructural (2022)El spalling es un fenómeno que sufre el hormigón expuesto al fuego debido al aumento de presión en los poros por evaporación y donde su superficie se desconcha incluso de forma explosiva durante los primeros 30 minutos de ... -
Effects of axial and rotational restraints on concrete-filled tubular columns under fire
Ibáñez Usach, Carmen; Romero, M. L.; Hospitaler, Antonio Elsevier (2016-10)This paper presents a study of the effects of axial and rotational restraints on the fire response of concrete filled tubular (CFT) columns. The fiber model presented by the authors in a previous paper Ibañez et al. (2013) ... -
Fiber beam model for fire response simulation of axially loaded concrete filled tubular columns
Ibáñez Usach, Carmen; Romero, M. L.; Hospitaler, Antonio Elsevier (2013)This paper presents a fiber beam model for the fire response simulation of concrete filled tubular columns of circular section under concentric axial load. The model consists of two parallel components, one with a circular ... -
Fire design method for concrete filled tubular columns based on equivalent concrete core cross-section
Ibáñez Usach, Carmen; Aguado, José V.; Romero, M. L.; Espinós, Ana; Hospitaler, Antonio Elsevier (2015)In this work, a method for a realistic cross-sectional temperature prediction and a simplified fire design method for circular concrete filled tubular columns under axial load are presented. The generalized lack of simple ... -
Influence of Ultra-high Strength Concrete on Circular Concrete-filled Dual Steel Columns
Romero, M. L.; Ibáñez Usach, Carmen; Espinós, Ana; Portolés Flaj, Jose Manuel; Hospitaler, Antonio Elsevier (2016-07)This paper presents the results of an experimental program where the load-bearing capacity at room temperature of 14 slender circular concrete-filled dual steel tubular (CFDST) columns under axial load was analysed. In ... -
Post-heating response of concrete-filled steel tubular columns under sustained loads
Ibáñez Usach, Carmen; Bisby, L.; Rush, D.; Romero, M.L.; Hospitaler, Antonio Elsevier (2019-04-29)Concrete-filled steel tubular (CFST) columns can generally be expected to better resist elevated temperatures as compared to unfilled steel hollow sections, whose evaluation after a fire is limited by the resulting ... -
Shape effect on axially loaded high strength CFST stub columns
Ibáñez Usach, Carmen; Hernández-Figueirido, David; Piquer, Ana Elsevier (2018-08)In this paper, the results of an experimental investigation of 12 concrete-filled steel tubular (CFST) stub columns subjected to concentric loads are presented. In this program, different cross-sectional shapes are considered: ... -
Slender double-tube ultra-high strength concrete-filled tubular columns under ambient temperature and fire
Romero, M. L.; Espinós, Ana; Portolés Flaj, Jose Manuel; Hospitaler, Antonio; Ibáñez Usach, Carmen Elsevier (2015)This paper presents the results of an experimental campaign where both the room temperature and the fire resistance of six double-tube concrete filled steel tubular slender columns with different combinations of concrete ... -
