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 ... -
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) ... -
Experimental residual capacity of steel-reinforced concrete-filled steel tubular stub columns after fire exposure
Medall Martos, David; Ibáñez, C.; Albero, Vicente; Espinós, Ana; Romero, M. L. Elsevier (2023)Technological advances in the development of steel–concrete composite structures have led to the introduction of novel types of sections in the sought of higher load-bearing capacities. Particularly for composite columns, ... -
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 Slenderness on High-Strength Rectangular Concrete-Filled Tubular Columns with Axial Load and Nonconstant Bending Moment
Hernández-Figueirido, David; Romero, M. L.; Bonet, J. L.; Montalvá Subirats, José Miguel American Society of Civil Engineers (2012)Forty-nine experimental tests were conducted on rectangular and square tubular columns filled with high-strength concrete (f'c=90 MPa) subjected to axial load and a nonconstant bending moment distribution. The test parameters ... -
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 ... -
Influence of ultra-high strength infill in slender concrete-filled steel tubular columns
Portolés Flaj, Jose Manuel; Serra, E.; Romero, M. 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 ... -
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 ... -
Non-constant biaxial bending capacity assessment of CFST columns through interaction diagrams
Espinós, Ana; Albero, Vicente; Romero, M. L.; Mund, Maximilian; Meyer, Patrick; Schaumann, Peter Korea Institute of Science and Technology Information (2019)The mechanical response of concrete-filled steel tubular (CFST) columns subjected to pure compression or uniaxial bending was studied in depth over the last decades. However, the available research results on CFST columns ... -
