Espinós Capilla, Ana; Romero, Manuel L.; Hospitaler Pérez, Antonio(Elsevier, 2010-08)
In this work, a nonlinear finite element three-dimensional model is presented and validated in order to study the behaviour of axially loaded concrete filled tubular (CFT) columns with circular cross-section exposed to ...
Ibáñez Usach, Carmen; Romero, Manuel L.; Hospitaler Pérez, 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) ...
Ibáñez Usach, Carmen; Romero, Manuel L.; Hospitaler Pérez, Antonio(Elsevier, 2013-11)
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 ...
Ibáñez Usach, Carmen; Aguado, Jose V.; Romero, Manuel L.; Espinós Capilla, Ana; Hospitaler Pérez, Antonio(Elsevier, 2015-11-01)
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 ...
