Résumé : |
The composite columns composed of steel tubes filled with concrete became
increasingly popular in structural applications around the world. This type of columns can offer many advantages. Moreover, today the possibility of producing concretes with higher compressive strengths allows the design of the thinner column section, which allows a surface on the ground more usable, then, it is necessary to improve current knowledge of the mechanical behaviour of the columns for a more effective use. The principal matters of interest were to study: effectiveness of the steel tube by confining the core concrete, and of various means of application of load to the column. To carry out this, lot of the experiments and the analyses of finite element were employed in association. The composite columns are subjected primarily to compressive forces, and at the bending moments Their behaviour is very complex because of the contribution of two materials: steel, and concrete. The objective of this work is to determine the resistance of the composite columns filled with concrete subjected to the various axial stresses, and to determine its bearing capacity. The study was limited to the composite columns of square, and circular hollow section filled with concrete, while being based on the effect of several factors such as: the twinge of the column, the thickness of the walls, the confinement of the concrete, and the resistance of the cross section under loading. The computation results were obtained by a numerical calculation fairly the software of programming Mapple et Potfire. |
