Additional Fire Exposure Time for the Effect of Spalling in Reinforced Concrete Columns
Peña, D.L.; Ibáñez, Carmen; Albero, Vicente; Hospitaler, Antonio Springer (2023)Concrete exposed to fire can experience spalling when the pore pressure increases due to water evaporation resulting in damage to part of the concrete cross-section which causes the loss of the initial cross-sectional ... -
Ambient and fire behavior of eccentrically loaded elliptical slender concrete-filled tubular colums
Espinós, Ana; Romero, M. L.; Portolés Flaj, Jose Manuel; Hospitaler, Antonio Elsevier (2014-09)This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete ... -
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 ... -
Fire design of slim‐floor beams
Romero, Manuel L.; Albero, Vicente; Espinós, Ana; Hospitaler, Antonio Ernst & Sohn (2019)Slim‐floor beams are a well‐known and cost‐effective solution that permits a significant reduction of floor thickness, and are increasingly used in industrial and commercial buildings. Since only their lower flange is ... -
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 ... -
Innovative solutions for enhancing the fire resistance of slim-floor beams: Thermal experiments
Albero, Vicente; Serra, E.; Espinós, Ana; Romero, Manuel L.; Hospitaler, Antonio Elsevier (2019-11-14)Slim-floor beams have attracted the attention of designers in the last decades, owing to their ability for supporting intermediate loads without increasing the floor thickness. However, the behaviour of this type of beams ... -
Internally fire protected composite steel-concrete slim-floor beam
Albero, Vicente; Serra, E.; Espinós, Ana; Romero, M. L.; Hospitaler, Antonio Elsevier (2021-01-15)The slim-floor beam is a composite concrete-steel beam fully integrated into the floor depth that was developed at the beginning of the 1990s. This composite beam presents a very good behaviour during the fire event ... -
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 ... -
