Performance Study of Concrete-Filled Steel Tubes
LMDC, Civil Engineering Département, Constantine 1 University, Algeria
Abstract. Concrete-filled steel tubes circular section columns are increasingly used in the design of modernmulti- stories structures. Investigations developed in recent decades confirm their beneficial use. They are used as astructural component system, given their excellent energy absorption and dissipation, or as a rehabilitation tool forrecovery of damaged components after a seismic event. They contribute through their performance to confer highstrength to elements, as high ductility and high rigidity, with a remarkable optimization of the used materials.
The main objective of this work is to review the principal models characterizing the behavior laws of concrete confinedby steel jacket. An analysis based on Samantha model was conducted to highlight the parameters affecting the sectionalbehavior, and to evaluate the gains in strength and deformation. A section strength capacity investigation is presented.
Results are compared with some codes recommendations.
This type of structure can be used in Algeria for rehabilitating old buildings, or strengthening reinforced concretecolumns to improve their structural performance. However, new regulatory measures should be considered in order tointroduce this compound element in the construction.
