Fire Performance of CFST, SRC and RC Frames
Applied Mechanics and Materials, 2011Failure mechanism and fire resistance comparison of concrete-filled steel tube (CFST) frames, reinforced concrete (RC) frames and steel reinforced concrete (SRC) fames are proposed in this paper when their bearing capacity and rigidity at room temperature are similar.

Stability Analysis for CFST Basket Handle Arch Bridge
International Conference on Transportation Engineering 2009, 2009A spatial finite element method (FEM) model was established to analysis the structural stability of an actual concrete filled steel tubular (CFST) basket handle arch bridge. Various factors affecting stability analysis were fully considered. Moreover, the influence of the rib inclination angle on stability was investigated in detail.

Research on Skeleton Curve of CFST Frame Structure
Applied Mechanics and Materials, 2012Concrete filled steel tubular (CFST) structure is a new type of structure. According to unified theory, hysteretic model of steel beam, reinforced concrete beam and CFST column have been chosen respectively, then nonlinear structural analysis program called IDARC is employed to determine skeleton curve of the CFST frame structure. Results obtained from

Effects of debonding on circular CFST stub columns
Journal of Constructional Steel Research, 2012Abstract Core concrete subjected to confinement effect from steel tube is the main advantage of concrete filled steel tubular (CFST) column under compression. However, this beneficial composite action could be weakened even destroyed by debonding, which is almost unavoidable as a common phenomenon in CFST structures and has not been considered ...

بررسی آزمایشگاهی رفتار ستون های مرکب CFST
2010Steel columns filled with concrete, so called CFST columns are kind of mega composite columns that poses greater mechanical and daynamic behavior. In recent years, due to this enhanced behavior, more and more are being used specially in tall structures. They also result in more cost effective and easy to construct structures.

Blast analysis of stand alone CFST column
Materials Research ProceedingsAbstract. The rise in terrorist attacks targeting various locations worldwide has underscored the importance of evaluating structures exposed to blast effects. Despite progress in the field, understanding the response of concrete-framed buildings to extreme loading conditions remains crucial before implementing any protective strategies.
