In this work, a non-linear three-dimensional finite element model is presented in order to study the behaviour of axially loaded concrete filled elliptical hollow section (CFEHS) columns exposed to fire. This study builds ...

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 ...
