This paper includes experimental and numerical study of the octagonal partially encased composite (PEC) columns specimens under axial and torsion loading. The major difference between them was the concrete reinforcement details. The parameters investigated in the experimental and numerical study were the type of reinforcement details, the failure mode, width-to-thickness ratio of flange, transverse links spacing and diameter. The results were presented as loaddeformation curves. Numerical model was validated using finite element method and the results indicated acceptable accuracy with tests results in the form of capacity and ductility. In the analytical phase, the experimental results in the compressive loading were compared with those obtained from CSA S16-14 and EN 1994-1-1 equations. Also, the new concrete confinement factor in proportion to the web width to thickness ratio was presented to octagonal PEC columns under pure compressive load. Furthermore, different types of retrofit of cross-shaped steel column including concrete encasement, use of stiffener plates and transverse links were investigated in this research. Results revealed that concrete confinement and use of transverse links had respectively the most and the least effect on increasing torsional capacity of the specimens.

“…In this case, various models and numerous methodologies have been published by Gan (2000), Banholzer et al (2005), and Dominguez (2005), but few works have been presented treating the cracked flexural reinforced concrete members by Au, Bai (2007) and Nayal, Rasheed (2006). For this raison, a particular importance has been given to this kind of work.…”

Abstract. This paper deals with the analysis of cracked flexural reinforced concrete structures with special highlighting of modelling the interaction between concrete and reinforcement. A new approach based on the bond stress distribution through the transfer length between the zero-slip and the cracked sections is proposed. Since the cracking phenomenon of concrete occurs, the fracture energy changes in order to appeal to the interaction between concrete and steel. The increment of stresses is evaluated by the bond-slip distribution by means of one-dimensional problem. Besides, the 2D nonlinear description of components behaviour, concrete and steel are considered. On numerical modelling level, the interaction property is obtained from a variety of fundamental pull out and push out tests, for the most part this phenomenon does not very well represent the bending members. For this object, this study presents a numerical approach, which can compute the distribution stresses at the steel-concrete interface near flexural crack in reinforced concrete beams. Finally, predictions made by the non-linear finite element analysis program and the non-linear material models for concrete, reinforcing bars and bond slip are in good agreement with the experimental results.
